About this episode

Buying someone else’s unfinished project can look like a bargain, but the hosts keep pointing to red flags that turn “cheap” into expensive labor. They describe how oil leaks, cracked cases, and hidden internal damage can force major teardown work, while sketchy wiring, junker titles, and neglected driveline service add risk. Diesel examples highlight deeper fuel-system problems (like VP44/CP4) and costly machining. The episode’s through-line: inspect carefully, verify claims, and do due diligence before you commit.

Technical Too Afraid to Ask
Term

mods

"thinking oh these are all the parts I'll add these are the mods I'll do"

“Mods” is short for modifications—changes made to a car’s stock configuration. In project-car buying, mods can be good upgrades, but they can also hide poor workmanship, incompatible parts, or wiring/fitment issues that show up later.

Term

common rail

"…dirt cheap common rail that he got… I mean he got he did get a really good deal on it…"

“Common rail” is a type of diesel fuel system. Instead of feeding fuel in a simple way, it uses a high-pressure fuel line (“rail”) and precise electronic control to inject fuel into the engine.

Term

head gasket

"…I forget what the problem was it's like a third gen Dodge right… it was I think he was doing a head gasket or something on it…"

The head gasket is a seal between the engine block and the cylinder head. If it fails, coolant and other fluids can leak or mix where they shouldn’t, and that can lead to serious engine damage.

Term

pistons

"…he pulled it apart and the cylinders like someone peamed the pistons…"

Pistons are the parts that move up and down inside the engine cylinders. Here, the hosts are saying the pistons/cylinder surfaces were messed up, which suggests the rebuild wasn’t done correctly.

Term

three stone hone

"…it's rust pitted like someone took a three stone hone down it…"

A “hone” is a tool used to roughen/finish the inside of an engine cylinder. A “three stone” hone uses multiple abrasive pads, and the goal is to make the cylinder surface ready for the piston rings to seal.

Term

rust pitted

"…there was water sitting on the top of the cylinder so it's rust pitted like someone took a three stone hone…"

“Rust pitted” means the metal got corroded in small spots. Inside an engine, that kind of corrosion can prevent parts from sealing and working properly.

Concept

makeshift in frame rebuild

"…like someone took a three stone hone down it like kind of did a makeshift in frame rebuild and then slapped it back together and sold it"

An “in-frame rebuild” means doing a major repair without fully taking everything out. The host’s point is that this one sounds like it was done in a rushed or improvised way, which can lead to the engine failing again.

Term

machine shop bills

"…you got a good deal on truck but you start trying to pay for machine machine shop bills…"

Machine shop bills are the costs for specialized machining work. If the engine needs that kind of work, the repair cost can jump fast and make the project less of a bargain.

Term

cylinder

"…which is what it would take in to freaking clean that cylinder up like it adds up like that…"

A cylinder is the engine’s chamber where the piston goes up and down and where the fuel burns. If the cylinder gets damaged, the engine may need to be machined and fitted with bigger parts.

Term

custom janky crap

"like dude that bill is going to add up quick like by the time you start talking about [412.7s] like undoing custom janky crap like it's not it's not a good deal anymore"

That phrase means someone did custom fixes or upgrades in a sloppy way. When you try to finish the project later, you may have to redo or remove that bad work, which gets expensive fast.

Term

sight unseen

"on the flip side we have the other test truck Vindi we bought that that was sight unseen [497.1s] so kind of like not an ideal situation which I would not recommend on a second gen these days"

“Sight unseen” means you buy the vehicle without checking it yourself. With projects or modified trucks, you can miss problems that only show up after you own it.

Term

leveling kit

"like we've done so much work to that like we had it had a crappy [515.8s] leveling kit we had to pull out the steering was all crap the interior was trashed"

A leveling kit is a suspension upgrade that raises the front of a truck to make it sit more level. It can affect how the truck drives and wears tires, especially if it wasn’t installed correctly.

Term

swap doors and body panels

"like there's so we had to swap doors and body panels and like we did a lot of stuff to it [521.1s] there's so we had to swap doors and body panels and like we did a lot of stuff to it"

Swapping doors and body panels is a body-repair approach used when parts are damaged, rusted, or mismatched. It’s labor-intensive and can also complicate alignment and fitment, which matters for both appearance and water sealing.

Term

out of Texas

"he bought a truck side unseen out of Texas and his friend a dealer set out no big deal"

People mention where a car came from because weather and road salt can affect rust. A truck from a drier area may have less rust, but you still need to check it.

Concept

buying a truck side unseen

"he bought a truck side unseen out of Texas and his friend a dealer set out no big deal"

“Side unseen” means buying without checking the truck in person. With a project vehicle, that can be risky because you might not notice what’s really wrong.

Term

misfires

"he tells me and I was just like an O2 that misfires everyone's a while I was like I was just like injectors aren't going to fix a misfire once in a while"

A misfire means the engine isn’t burning the fuel in one or more cylinders the way it should. It can make the truck run rough and usually shows up as an error code.

Term

injectors

"he tells me and I was just like an O2 that misfires everyone's a while I was like I was just like injectors aren't going to fix a misfire once"

Injectors are the parts that spray fuel into the engine. If they’re not working right, the engine can misfire or run poorly.

Term

VP death codes

"on a VP truck it probably has VP death codes and it's probably like oh no no I know what I'm doing whatever"

“Death codes” is slang for error codes that show a serious problem. The idea here is that the truck may need more than a quick part swap because the underlying system is failing.

Term

VP 44

"and you buy the truck one really it needed a VP 44 now if you can install on yourself"

“VP44” refers to a particular diesel fuel injection pump. If someone says it needed a VP44, they’re saying the pump was the real problem, not just a cheaper fix.

Term

t-case

"why does that mean the rear end's about to go out because they never service the diffs the t-case smoked original"

The transfer case is the part that sends power to the front and rear wheels on 4WD trucks. If it’s not maintained, it can start making noise or cause problems engaging 4WD.

Term

differentials

"why does that mean the rear end's about to go out because they never service the diffs the t-case smoked original"

A differential is what lets the wheels turn at different speeds, especially when you’re cornering. If it isn’t serviced, the gears and bearings can wear out faster.

Term

dual cp3s

"he'd find one with compound turbos and dual cp3s and all this and he'd only have to give the guy about 5 000 more than"

CP3s are diesel fuel pumps. “Dual CP3s” means there are two fuel pumps, usually to support more power—more hardware to maintain.

Term

compound turbos

"he'd find one with compound turbos and dual cp3s and all this and he'd only have to give the guy about 5 000 more than"

Compound turbos mean the engine uses two turbo setups working together. They can make more power, but they’re more complicated and can be harder to keep reliable.

Car

Lancia Delta

"...essentially the same price he paid for it and his delta was the performance parts now he wanted a hot rod..."

The Lancia Delta is a small hatchback car. Some versions can be made faster and more performance-oriented with added parts, which is why someone might start with one and then build it into a “hot rod.”

Term

ball joint problems

"basically a two or three year old truck you're not going to have ball joint problems in two or [812.6s] three you're not going to have diff problems"

Ball joints are small parts in the suspension that help the wheels move and steer smoothly. If they wear out, the ride can feel loose and tires may wear unevenly.

Term

diff problems

"three you're not going to have diff problems you can tell if the paint and interior good because [816.7s] it's not even old enough to be rusted"

A “diff” is the part that helps the wheels turn at different speeds when you’re cornering. If it has problems, you might hear noise or feel vibration while driving.

Concept

secondary market of sellers

"there's a lot of um in the aftermarket or the [829.7s] i don't know the aftermarket it's not aftermarket but you know the secondary market of sellers you [834.5s] know you know your facebook ads your local classifieds whatever it might be"

The secondary market is where used cars are sold by people who aren’t the first owner. When you’re buying a project, it can be harder to know the car’s true history.

Term

vehicle history

"they really don't have a good knowledge of the vehicle history [888.0s] vehicle and their purpose is really just to make some cash"

Vehicle history is basically what’s happened to the car before you. If you don’t know it, you might miss clues about accidents or repairs that weren’t done right.

Term

single cab

"8000 dollar oh six work truck that was a single cab uh-huh like [903.6s] race truck"

A single cab means the truck only has front seats and no back doors. It usually leaves more room for cargo and work equipment.

Term

crank of windows

"that one has a crank of windows yeah it's a perfect truck for racer is that the one down in [912.1s] st george"

“Crank of windows” means the windows go up and down by hand. That usually shows the truck is a simpler, more basic work setup.

Term

engine swap

"there's actually a third category and that's the true project guy where you're going to pull that engine anyway... if for example you're the engine swap you're going to put a built transit anyway you're more looking at body panels to be straight and rust"

An engine swap means putting a different engine into a car or truck. It’s more than just dropping in a new motor—you usually have to make a bunch of other parts work with it too.

Term

built transit

"if for example you're the engine swap you're going to put a built transit anyway you're more looking at body panels to be straight and rust"

A “built” transmission means the gearbox internals have been upgraded to survive harder driving or more engine power. It’s not the factory setup.

Term

carbon fiber doors

"if you're going to put carbon fiber doors on your truck you don't care if the doors are rusted out right"

Carbon fiber doors are lighter doors made from a strong composite material. They can be part of a performance build, but they’re usually more costly than regular doors.

Term

race truck

"and if the interior is all ready and you're going to gut it should build a race truck you don't care"

A “race truck” is built mainly for racing. In that case, people often focus on performance and don’t worry as much about appearance.

Term

street truck

"but if you're trying to build a nice street truck and you care about body and paint you're going to you know you're going to buy a cleaner truck"

A “street truck” is a truck meant for normal driving on public roads. If you’re building one for the street, you usually care more about how it looks and how clean it is.

Term

rust repair

"if you're a body shop and you don't mind doing rust repair you might find a truck that's mechanically solid as a rock"

Rust repair means fixing corrosion on the car. If rust is bad, it can be a big job and cost a lot of time and money.

Term

ball joints

"mechanically solid as a rock it's got all the ball joints and everything all fresh engines all great"

Ball joints are parts in the suspension that help the wheels move and steer properly. If they’re worn out, the ride can feel loose and tires can wear unevenly.

Term

pop the hood

"so one thing like a couple things i when i pop the hood i'm looking for first of all the hood insulation and the cow insulation"

It just means opening the hood so you can look at the engine area. The hosts are saying you should inspect things before buying a project.

Term

hood insulation

"i'm looking for first of all the hood insulation and the cow insulation if it looks crisp you know that this thing has"

It’s the padding under the hood. If it’s loose or falling off, it can be a clue the car hasn’t been cared for or put back together correctly.

Term

firewall

"second is like a firewall the oh yeah we're talking yeah and the headliner yeah"

The firewall is the wall between the engine area and the inside of the car. If it’s been repaired badly, it can be a warning sign about the project’s history.

Term

headliner

"second is like a firewall the oh yeah we're talking yeah and the headliner yeah another common one which i think it's a lot of people is leaks"

The headliner is the interior fabric/trim on the roof. Water intrusion from leaks can stain or sag it, so checking it helps you spot hidden leak problems early.

Term

pull the trans

"pay on the leak it could actually be kind of sucky like you either got to pull the trans for the remain"

It means taking the transmission out of the way to reach the leaking part. Even if a leak seems small, the repair can be a big job.

Term

pull the pump off

"you either got to pull the trans for the remain you got to pull the pump off for the tap cover"

It means removing a pump to get to the part that’s leaking. That usually takes more work than people expect.

Term

pull the front apart

"or you got to pull the front apart for the kdp like the case cracked or front cover"

It means you have to take apart the front of the vehicle to reach the problem. That’s usually a sign the repair will be more time-consuming and costly.

Term

case cracked

"or you got to pull the front apart for the kdp like the case cracked or front cover like whatever yeah there's several"

“Case cracked” means the metal housing is broken. That usually isn’t a quick fix—you often need to replace the damaged part.

Term

oil leaks

"just about to get into with the whole oil leaks thing is first of all they suck to fix yeah second of all like some of that you can suck to fix sometimes it's super easy problems the second thing though is that if it's leaking a bunch of oil that owner probably didn't care about it"

An oil leak means oil is escaping from the engine or related parts. It’s important because small leaks can turn into bigger problems, and they can also be messy and expensive to track down.

Car

Toyota 4Runner

"you get vehicles like i i think back to a couple of the vehicles i've owned over the over the years and one that always stands out to me was this old toyota um uh forerunner and it that thing pissed me off like i had my i on my tow truck i painted the engine i did a bunch of nice stuff to it"

The Toyota 4Runner is a rugged SUV that many people keep for a long time. Here it’s used as an example of how to inspect a car—especially by popping the hood and checking what’s been worked on.

Term

OEM radiator

"and he's like oh this thing's hard to do this and so i replaced it i replaced that and put like like a oem radiator and stuff like that"

An OEM radiator is a replacement radiator made to match the original one. It’s often chosen because it fits correctly and is designed for the car’s cooling system.

Term

oil changes

"who what else are they not dealing with and not maintaining i mean that guy probably the guy that's leaking from three different spots also probably doesn't do his oil changes on time that Toyota guy i think he said he did every 7000 miles"

Oil changes are when you replace the engine’s oil. In this context, they’re used to judge whether the previous owner took care of the car regularly.

Term

wiring

"another thing i look at when i i mean i like to pop the hood obviously but what kind of wiring have they added oh my yes and how did they add it"

Wiring is how the car’s electrical systems are connected. If someone used sloppy temporary wiring, it can cause problems later and be unsafe.

Term

electric fan

"when i was first building it i needed someone commented was said we need to bring the timer back so i i needed to add an electric fan in the back and i didn't have a wire at that time"

An electric fan is a fan that runs on electricity to help cool the car. Builders sometimes add one temporarily when they don’t have the right wiring or parts yet.

Term

trans cooler

"no it was a trans cooler so i mean what else i could do okay so actually i'm gonna have a stance on this"

A transmission cooler is like a radiator for the transmission. It helps keep the transmission from getting too hot, especially when you’re driving hard.

Concept

unfinished project

"but if you're looking to buy some a project to enjoy and have free worries if the title is junker you may stay away from that"

An unfinished project means someone started fixing or building the car, but didn’t finish. You’re basically buying a “work in progress,” so there can be surprises you can’t see right away.

Concept

junker title

"and have free worries if the title is junker you may stay away from that yeah for sure"

A junker title usually means the car has a serious history—often it was totaled or heavily damaged. That can make it harder to insure or resell, and it may hide repair problems.

Term

extension cord

"i just feel like it's hurts me because i feel like extension cord does get like a super bad rap"

They’re talking about sketchy, temporary-looking wiring—like using something that isn’t meant to be in a car. That can cause problems later, especially with heat, vibration, and movement.

Term

loom

"it's better than these two single wires dangling up and down the frame hooping between things because a lot of people they'll buy wire from auto zone and do that and it's not she it rubs and arcs over time"

A loom is the protective sleeve/cover for car wires. If wires aren’t protected and are left exposed, they can rub against metal and wear out.

Term

arcs over time

"and it's not she it rubs and arcs over time or that it's crimp connected you know in the butt splice connectors get loose"

Electrical arcing is when electricity “jumps” where it shouldn’t, usually because of a bad connection or damaged insulation. In a car, that’s a serious problem because it can lead to failures and safety hazards.

Term

butt splice connectors

"and it's not she it rubs and arcs over time or that it's crimp connected you know in the butt splice connectors get loose"

Butt splice connectors are the common “wire joiners” used to connect two wire ends. If they’re done poorly, they can come loose and cause electrical problems.

Term

crimp connected

"and it's not she it rubs and arcs over time or that it's crimp connected you know in the butt splice connectors get loose"

Crimp connected means the wire is joined with a metal connector that’s squeezed on. It works best when it’s done with the right parts and tools; otherwise it can fail later.

Term

zip ties

"and like it's easy to look at that those things and say like hey like i can fix that just like i can do that for two dollars five dollars i can freaking click to clean that up"

Zip ties are plastic fasteners used to hold things in place. If someone only uses zip ties to route car wires, the wires can still rub and wear out.

Concept

back half

"it was this like late 60s muscle car that somebody had back half and i crawled under there and looked at it"

“Back half” means the rear part of the car has been cut out and replaced or rebuilt. The quality of that work matters because it affects how solid and safe the car is.

Term

scabby welder

"and i crawled under there and looked at it and i'm kind of a scabby welder a little bit i'm getting a little bit better but i've done some some wtf you know will terry fab stuff"

“Scabby welder” is a slang way of saying the welding looks rough or poorly executed. In a project car, rough welding can indicate weak structural repairs, poor penetration, or inconsistent metalwork that may fail later.

Concept

fabrication work

"will terry fab stuff i'm not impressed or i'm not proud of i looked under this car and i was like just like if the back half looks this bad there's no way the motor or whatever else in this car"

Fabrication work is custom building or repairing metal parts. If the welding/metalwork looks rough, it often suggests the rest of the project may have similar quality issues.

Concept

walk away

"and and redid it and i was just [1556.1s] like so sometimes the right answer is to just walk away that doesn't always rain true like there's"

It means you decide not to buy the project at all. If the work already done looks sketchy, it can turn into a huge money-and-time pit.

Term

welds

"like there's [1561.7s] a guy that has a car that he's worked on a bunch and you look at the welds and some of the fab work"

Welds are the spots where metal was fused together. If the welds aren’t done well, the car structure can be weaker and problems can show up later.

Term

fab work

"and you look at the welds and some of the fab work [1565.4s] there it's like eh but he can machine a heck of a block so like sometimes you just gotta like know"

“Fab work” means custom metal building or modifications. If it’s sloppy, you may need to redo it before the car is solid and safe.

Term

electrical gremlins

"so i mean electrical gremlins can really bite you though [1613.9s] like literally like if there's junkie they've got especially gone to the harness"

“Electrical gremlins” are weird electrical problems that come and go. They can be hard to find, so they often cost more time and money to fix than you expect.

Term

engine harness

"like literally like if there's junkie they've got especially gone to the harness [1617.8s] like the actual engine harness if you see things popping out of that guy like the scotch locks"

The engine harness is the big bundle of wires that runs to the engine sensors and components. If it’s been messed with, electrical problems can be very hard to track down.

Term

scotch locks

"if you see things popping out of that guy like the scotch locks [1621.8s] where they just pop together yeah like they'll take quick caps or whatever"

Scotch locks are quick wire connectors people use to tap into existing wiring. They can work short-term, but they often become unreliable and cause electrical issues later.

Term

grounds

"say like here check your grounds where do i start there's a bundle of 100 wires there yeah and so [1675.0s] yeah like you start getting people messing with wires nah so when i pop a hood i'm hoping to see"

“Grounds” are the electrical connection paths that let electricity flow correctly back to the battery. If they’re loose or corroded, the car can act weird and throw electrical problems.

Term

rat's nest

"and you can you know or little things happen in these older trucks but if you see a rat's nest [1692.0s] under there man i'd be very leery of the truck like that but if you're good at wiring yeah i may not"

A “rat’s nest” is tangled, messy wiring. It usually means the electrical work is hard to trust and will be a pain to diagnose and fix.

Term

transfer

"other things you need to check about mechanically wise and check the oil check [1743.5s] the transfer as it come out red as it come out brown smell burnt and nothing else when you take [1748.2s] that transmission dip stick out"

The “transfer” is the part that sends power to all four wheels on a 4x4 truck. Checking its fluid helps you spot if it’s been neglected or is running hot.

Term

transmission dip stick

"and nothing else when you take [1748.2s] that transmission dip stick out and you put up to your nose like my wiffer doesn't work but i do [1751.4s] it anyway because it makes me feel really cool"

The transmission dipstick lets you check the fluid in the automatic transmission. If the fluid smells burnt or looks bad, it can mean the transmission has been abused or is failing.

Term

mechanical linkage

"or something and it would just put itself in neutral i'm like that's weird i mean some mechanical linkage like puts itself in neutral i'd never seen this before"

Mechanical linkage is the “moving parts” system that transfers motion—like rods or levers that make something move when you move a control. If it’s loose or damaged, the car can behave strangely.

Term

hot rod

"i see commonly a lot of guys want a hot rod maybe they pull the engine you know hot rod truck they buy a roller"

A hot rod is a car that’s been modified for fun—often with upgrades to make it more exciting to drive. Here it’s describing the kind of project people want to build.

Concept

roller

"they pull the engine you know hot rod truck they buy a roller it's a lot easier i think sometimes to buy a roller because you're not paying a premium for an engine that you may not know anything about"

A “roller” is basically a chassis/vehicle without the engine (and sometimes other big parts). Builders like it because they can choose what engine and parts to install instead of inheriting someone else’s unknown setup.

Term

burnout truck

"you know maybe it's a a back tap race truck or maybe it's a burnout truck or maybe it's a really nice street truck"

A burnout truck is meant for doing burnouts, where the tires spin and smoke. Building for that kind of use can change what parts you need and how hard you’ll stress the drivetrain.

Term

front main seal

"they're like oh it's just got a little oil like no big deal front main seal and they had no idea that actually the killer dowel pin had fallen on this 12 valve cracked the case"

A front main seal is a gasket/seal that keeps engine oil from leaking near the front of the engine. If the job is more than just that seal, it usually means you have to open up more of the engine than expected.

Term

dowel pin

"they had no idea that actually the killer dowel pin had fallen on this 12 valve cracked the case"

A dowel pin is a small alignment pin that helps keep engine parts in the right spot. If it comes loose, it can cause major damage because the parts may no longer line up correctly.

Term

12 valve

"the killer dowel pin had fallen on this 12 valve cracked the case and to fix that you have to pull the whole"

“12 valve” refers to an engine head design where there are 12 valves total (commonly 3 per cylinder on a 4-cylinder or 2 per cylinder on a 6-cylinder, depending on the engine). It’s a specific engine configuration that enthusiasts use to identify the exact motor generation and design.

Term

pull the front cover

"and to fix that you have to pull the whole you know radiator and everything out pull the front cover off and you have to pull the cam shaft out"

Pulling the front cover means taking off the front housing of the engine so you can reach parts inside. It’s usually not a quick job because it opens up access to the timing/front internals.

Term

cam shaft

"pull the front cover off and you have to pull the cam shaft out which means someone's got to hold the lifters up"

The camshaft is the part that controls when the engine’s valves open and close. Taking it out usually means a bigger repair job and careful reassembly.

Term

lifters

"which means someone's got to hold the lifters up which means and it's like it's not just a front main seal"

Lifters are parts that help move the valves when the camshaft turns. If the camshaft comes out, lifters can shift, so the mechanic may need to keep them in place while working.

Term

bag of bolts

"six oh i i would be struggling trying to think of like okay there's this bag of bolts like what does it even go to if i'm lucky"

A “bag of bolts” refers to loose fasteners that were removed during disassembly and stored without clear labeling. For a buyer, unlabeled hardware increases the risk of using the wrong bolts in the wrong locations, which can cause fitment issues or even damage to threaded parts.

Term

10 millimeter sockets

"you'll find like 10 millimeter sockets mixed in there like all the common wrench sizes that you're just $5 for the tools really help offset"

A 10mm socket is a tool size that fits a lot of common bolts on many cars. The idea here is that 10mm tools are so common that they’re often still around even in messy project-car tool piles.

Brand

Snap-on

"you're just like oh snap on wrench doesn't match my my harbor frame you know i'm gonna slide it in there though"

Snap-on is a well-known brand of mechanic tools. The point is that if the previous owner had different tool brands, your tools might not fit together as neatly, and you may have to buy missing pieces.

Brand

Harbor Freight

"oh snap on wrench doesn't match my my harbor frame you know i'm gonna slide it in there though"

Harbor Freight is a store/brand that sells cheaper tools. If your project car came with Harbor Freight tools mixed with other brands, you might find gaps or mismatches that slow you down.

Brand

Pittsburgh Pro

"i'm gonna slide it in there though i'm gonna take my Pittsburgh pro 12"

Pittsburgh Pro is a tool line from Harbor Freight. The takeaway is that the tools you inherit with a project car might not be a complete, matching set.

Brand

Craftsman

"i don't even put this craftsman 12 in here or this snap on"

Craftsman makes tools that many people have at home. Here it’s mentioned to show that tool brands can be mixed, and you may still need to buy the right ones.

Term

interiors

"we've done interiors here like just ready interiors we pulled out new foam new cushions yeah new leather and looked freaking amazing"

In this context, “interiors” means the inside of the car—seats and upholstery. The host is saying interior fixes can be easier to tackle than engine work.

Part

foam cushions

"we pulled out new foam new cushions yeah new leather and looked freaking amazing"

Foam cushions are the padding in the seats. If they’re worn out, the seat can feel saggy, so replacing them can make the interior feel new again.

Term

due diligence

"i'd hate to see people burn money on a bad vehicle or they could have what they wanted if they just did a little more due diligence"

Due diligence means doing your homework before you buy. On a broken project, it’s checking what’s wrong and what you’ll need so you don’t get surprised later.

Term

turn them up

"and then researching a 12 valve fuel system how to fix those fuel system issues i learned that you can turn them up"

In this context, “turn them up” means increasing the engine’s fueling/boost-related settings to make more power. On diesel project builds, that can be done, but it also raises stress on components, so it’s a common “trap” if the rest of the setup isn’t ready.

Term

manual transmission

"and so then i was like okay well i'm gonna leave this one stock but i'm gonna buy another one and um it's gonna be a manual it's gonna be four by four"

A manual transmission is the kind where you use a clutch pedal and shift gears yourself. The speaker prefers it over an automatic for their project.

Term

four by four

"it's gonna be a manual it's gonna be four by four and it's gonna be my project"

“Four by four” means the truck drives all four wheels. That can make the truck more capable, but it also adds more parts that can be missing or broken in a project.

Term

junkyard

"i was like oh i'll just buy this one out of a junkyard it was rolled over paid 1200 bucks for it with engine trans everything"

A junkyard is where you buy used cars or parts. It can be cheaper, but you might discover important pieces are missing once you start the project.

Term

rolled over

"it was rolled over paid 1200 bucks for it with engine trans everything"

“Rolled over” means the truck flipped over. That can cause damage you can’t easily spot, so it’s riskier to buy as a project.

Term

hybridizing parts

"and so then i bought a v10 for 1100 dollars and started hybridizing parts and then because it was in a junkyard i found out really quickly that a lot of parts were missing"

They’re combining parts from different trucks to make one project work. It can help you finish a build, but it can also create problems if the parts don’t match up.

Term

bolt sizing

"because of that i got really good at bolt sizing so if you ever need to know the bolt size on anything i'm your guy"

Bolt sizing means using the right bolt dimensions for the job. If the bolts are the wrong size, things may not tighten properly or can get damaged.

Term

cold air intake

"diesel tow trucks i wouldn't be afraid of a truck that's a cold air intake to me no whatever that's there's no"

A cold air intake is a modification that tries to feed the engine cooler air. It can be fine, but if you drive in dusty conditions, the intake setup and filter quality matter a lot.

Term

engine wear

"i would be a little bit wary going like all right it probably has a little bit higher rate of engine wear because the k&n filter doesn't filter that great"

Engine wear is how the engine slowly gets less healthy over time. Dust and poor filtration can make that happen faster.

Term

K&N filter

"if it's a k&n filter and they live on a dirt road and it's eight dirt its whole life i would be a little bit wary"

A K&N filter is a reusable air filter. In dusty driving, the filter has to catch a lot of dirt—if it doesn’t, the engine can wear faster.

Term

blow by

"but but that's about the only thing i think of when i see an air intake i don't think this is a race truck ... i might be a little bit wary to have a little extra blow by"

Blow-by is combustion gases leaking past the piston rings into the crankcase. Excess blow-by can indicate ring or cylinder wear, and it’s a red flag when evaluating an engine that has been modified or run hard in harsh conditions.

Brand

Banks

"bone stock is like the any banks part you know that they're not serious performance enthusiasts"

Banks is a company that makes aftermarket parts for diesel trucks. The point here is that their parts are usually more expensive, so they can hint the previous owner invested in the truck.

Term

6064s

"like if i saw a truck that had one of our 6064s in it"

“6064s” sounds like a specific turbocharger type. The host is basically saying that certain turbo choices usually mean the truck was built for real performance.

Term

turbocharger

"obviously it's got bigger turbo they probably wanted more power and so that that could be a [2337.6s] sign that they're wanting to beat the crap out of it more generally like they beat the crap out of [2341.5s] more i feel like that really does like oil leaks and stuff follow with that"

A turbocharger is a device that forces more air into the engine, which can make more power. If a truck has a turbo and it also has oil leaks, it can be a sign the turbo setup wasn’t cared for.

Term

drop-in turbo

"if it's like leak free i'm like okay they bought a drop in turbo like their turbo probably failed or something like [2349.8s] and they picked a decent unit then just go to ebay and get some freaking whatever cheap option"

A “drop-in turbo” is a turbo that’s supposed to install pretty easily, without lots of custom parts. If someone installed a cheap one, it can mean they were trying to fix a problem fast instead of doing everything correctly.

Term

T4 S 300

"it's not really that t4 s 300 it's not [2372.6s] really an upgrade but you justify that yourself when you're buying the truck"

“T4 S 300” sounds like a specific turbo type/size. The host is saying that particular turbo may not be a meaningful improvement, so you can’t judge the build just by the turbo being “bigger.”

Term

Aggressor 6064

"if you specifically [2377.5s] wanted an aggressor 6064 and it has it on there and the truck didn't really cost more than one [2384.1s] without it then that's a bonus you got a freaking sweet turbo"

“Aggressor 6064” is a particular turbo model. The point is: if the truck already has the exact turbo you wanted, that’s a bonus—even if the seller didn’t pay extra for it.

Term

compounds

"if i was trying to buy a truck and it had compounds on it that's a risky game someone spent the time and [2399.6s] money installing those they probably wanted to beat the crap out of it"

“Compounds” here means the truck has more than one turbo working together. That setup is more complicated, so if it’s not done well or was driven hard, you’ll often see problems like leaks.

Term

mismatched valve covers

"if i saw a truck that had compound turbos [2451.2s] and had oil leaks and mismatched valve covers and that one was match tires i'd be like all right"

If the valve covers don’t match, it can mean someone replaced parts at different times or used whatever was available. That’s a clue the job might have been rushed or not fully sorted out.

Concept

commercially available kit

"quality of fabrication makes a big difference and if it's a commercially available kit it's gonna be good and as long as it's been maintained well it's probably designed properly"

A commercially available kit is a turbo upgrade that’s sold as a complete package. It’s usually designed to work together, which can be safer than a one-off homemade setup.

Term

four-digit power

"i beat the tar out of it if i sold that to somebody i'd be like there's no warranty the engine could blow up tomorrow or it might be good for 10 years i don't know all i know is it's making four-digit power"

“Four-digit power” means the truck is making 1000+ horsepower. When a car makes that much power, it often wears parts out faster and can be less predictable.

Term

boost

"just because i think it makes for me makes like 112 115 pounds of boost okay i'm sure it does you're just used to the junker drag truck being so light"

Boost is how much extra pressure the turbo adds to push air into the engine. More boost usually means more power, but it also puts more strain on parts, so longevity can drop.

Concept

expected life expectancy

"anyone buying any vehicle 1100 horse or about let's just say above a thousand or even above 800 like you're buying something that has an expected life expectancy like yeah who knows how much is left"

The hosts are discussing how heavily modified, high-boost vehicles don’t have a predictable “expected life expectancy” like stock cars do. At very high power levels, wear and failure risk depend heavily on how the vehicle was built, tuned, and maintained.

Term

rod knock

"yes it's got a funny noise i'm gonna do just one more just to make sure that that doesn't fix the noise okay it definitely has a rod knock but if i sell it while the engine's still cold it doesn't knock so i can get premium dollar for sale"

Rod knock is a bad-sounding rattle from inside the engine. It usually means something inside is worn out, and it can turn into expensive engine damage.

Term

aftermarket

"so things be afraid of things not to be afraid of after market i mean a new transmission in a dodge truck it's gonna happen you're gonna hopefully you got a fresh winner a good build"

Aftermarket just means parts that weren’t made by the car’s original brand. They can be great upgrades, but you want to confirm they were installed correctly and have receipts or proof of quality.

Term

built transmission

"if it's a built transmission you're like oh my gosh i'm saving $10,000 to build transmission that's a pitfall to me think of it as basically a fresh stock unit when you see it's it's built now if they have a receipt from us or some other reputable builder"

A built transmission means someone upgraded the inside parts of the automatic transmission. It can be a good sign, but you need to know who built it and what they used.

Term

inspection cover

"and you know exactly what's in there you can pull the inspection cover off on your four speed and see that it has the right color of torque converter"

An inspection cover is a panel you can remove to peek inside a component. Here, it’s used to verify what parts are actually in the transmission.

Term

four speed

"you can pull the inspection cover off on your four speed and see that it has the right color of torque converter"

“Four speed” means the automatic transmission has four forward gears. It’s just describing the transmission’s gear count.

Term

warranty

"like yeah the guy paid $6,000 for it and you're like oh it may or may not have a warranty still so confirm with whoever he says build it to confirm that"

A warranty is a promise that if something breaks, the shop will fix it. But with some transmission work, that promise may only apply to the original buyer, not the next owner.

Term

torque converter

"might have our torque converter in it or it might have one of our pans on it or something ... it's very common to find one with an aftermarket torque converter because it's probably been rebuilt at some point"

On an automatic transmission, the torque converter is the part that helps the engine’s power get to the transmission smoothly. If someone swapped in an aftermarket one, it usually means the car has been modified before, but you still need to verify the overall work.

Term

input shaft

"find one with an aftermarket torque converter ... generally it's not common to buy a truck and open it up and find a bill and input shaft and a bunch of nice parts"

The input shaft is a key internal part that takes power coming into the transmission and sends it deeper inside. If a seller only has a few upgraded parts, it may not be a full “built” transmission.

Term

heavy duty transmission

"the guy said i had this heavy duty transmission a towing transmission ... it's a very mildly upgraded transmission basically stock"

“Heavy duty” can sound like a big upgrade, but sometimes it’s only a small change. You still need to confirm what was actually upgraded and whether it matches the use you want.

Term

thrust washer

"yeah exactly we did that one is the the thrust washer or something oh that's right yeah it"

A thrust washer is a small internal part that helps keep moving parts positioned correctly inside the transmission. Replacing it can be part of a rebuild, especially if wear or clearance issues are present.

Concept

fifth gen vs fourth gen

"…you can get a 2019 to like 2021 fifth gen for cheaper then you can get a 2015 to 2018 fourth gen and because people that know know that already has the flat tapets in it…"

“Fourth gen” and “fifth gen” refer to different generations of a truck platform, and in this discussion they’re tied to engine hardware changes. The hosts are using generation to explain why certain years are cheaper or more desirable based on what lifter design they use and what problems owners may face.

Term

flat tapets

"…because people that know know that that already has the flat tapets in it it's got really solid… a lot of enthusiasts are skipping the 19 and newer right because they don't want to deal with the flat tapet because that being the parts themselves are a couple grand…"

“Flat tapets” are a specific style of lifter inside the engine that rides on the camshaft. If they wear out or fail, repairs can get very expensive, which is why people pay attention to which trucks have them.

Term

push rod

"with on the push rod too where um the push rod because they inverted the the cup so normally [2998.1s] on which i never even thought about this yeah but on a 12 valves forever 12 valve 20 vp common"

The push rod is the link that moves motion from the lifter to the rocker arm. If it’s worn or its oiling design isn’t working right, the valve system can run dry and wear faster.

Term

dry starts

"now you've got this inverted cup that's upside down and off you've ever taken a cup and like unless it's like a smoothie or a blizzard from Dairy Queen the crack falls out and now you're doing a bunch of dry starts and you'll wear out that top"

A dry start means the engine starts before oil reaches the moving parts the way it should. That can increase wear and lead to ticking or other problems.

Term

valvetrain

"so then it gets clearance which then makes just the roller lifter can't pump up enough yeah so then it hammers every time it cracks so you hear a small tick"

The valvetrain is the set of parts that controls when the engine’s valves open and close. If those parts wear or don’t get enough oil, you can hear ticking and the engine can run worse.

Term

flat tappet

"the whole crux of it is from 1989 through 2018 it had a flat tap it so it's a mechanical solid flat there's a cast cam with a cast tap it a push rod"

A flat tappet is a type of lifter that rides on the cam. If it doesn’t get enough oil or if clearances are wrong, it can wear out and start making noise.

Term

valve lash

"from 1989 through 2018 it had a flat tap it so it's a mechanical solid flat there's a cast cam with a cast tap it a push rod and there's a push rod adjuster on the rocker arm and you adjust your valve lash every on these later models every every 100000 miles is the interval"

Valve lash is the tiny gap in the valve mechanism that needs to be set correctly. If it’s off, the engine can run poorly and parts can wear faster.

Term

flat tap at conversion

"right now the fix is to do a [3129.9s] flat tap at conversion and so you're basically going back to the old style cam"

They’re describing a change to how the cam and lifters contact each other. It’s done to avoid a failure-prone setup, but it usually means you have to do more regular adjustments afterward.

Company

Dodge

"so much i was talking to a tech and basically they're having such a shortage [3152.4s] of parts that dodge was saying you can go to the aftermarket and buy aftermarket fixes for this"

Dodge is the vehicle manufacturer being discussed. The speaker says they were dealing with parts shortages and allowed certain aftermarket solutions instead.

Term

CP4

"um back so 2019 to 2024 i think [3171.7s] has the roller i mean obviously 2025 still has it so i don't know if they change anything in those [3175.4s] the new engines but either way um the 2019 also got a cp4 and those guys have where all [3182.9s] sorts of issues"

CP4 is the name of a high-pressure fuel pump used on certain diesel engines. In some years/engines it’s known for failing, which can lead to major repair costs.

Term

high rail pressure

"everybody runs it has more flow to it that way you know help support whatever handle higher [3221.7s] rail pressure"

In a diesel common-rail system, rail pressure is how hard the fuel is pushed through the fuel lines. Higher pressure helps the engine control fuel delivery more precisely.

Term

recall

"still doing the recall they'll still put a cp3 in for you but um that's a 2019 2020 thing"

A recall is when the company admits there’s a problem with certain cars and offers a fix. The dealer can do the repair so the truck is brought up to the safe/updated standard.

Concept

model-year risk (newer trucks cheaper than older ones)

"that's why these newer ones are cheaper than the 15 through 18s because people that know no enthusiast know that there's a little bit more work"

Sometimes newer trucks cost less because people expect there could be problems that haven’t been fully figured out yet. If you’re an enthusiast, you might be willing to deal with that risk for a better deal.

Term

stiffer frame

"because it's a nicer truck that's why i realized it's better for towing it's a stiffer frame it's got better brakes"

A stiffer frame means the truck’s body/chassis flexes less when you’re towing. That can make the truck feel more stable and easier to control.

Term

better brakes

"it's a stiffer frame it's got better brakes it is a better truck other than the engine problems"

Better brakes means the truck can stop more strongly and more consistently, especially when you’re towing. It’s an important upgrade when you’re carrying heavy loads.

Concept

engine problems vs building an engine

"it is a better truck other than the engine problems and to you you're going to build either engine on either truck"

Some trucks have known engine issues, but if you can work on them yourself, you can fix or rebuild what’s wrong. The host is saying that changes whether the truck is a good deal for you.
