About this episode

A lively Auto Off Topic catch-up turns into a real-world wrenching saga: a 2000s Mitsubishi Lancer OZ rally that passed emissions after a bulb fix, then developed slow starts and finally a no-start. After swapping fuel pump, cam/crank-related sensors, and fighting a buried crank sensor behind the timing belt, the culprit ends up being the crank sensor—then it fires back up after priming. The hosts also play “cray-crayed” with wild car listings (including a twin-carb Honda Prelude) and wrap with NASCAR/Darlington and Sebring talk.

Technical Too Afraid to Ask
Term

coolant

"[38.5s] 1980 Volvo horns what's right man's coolant he's like oh I thought I'd be small it's for a [45.2s] small car and oh yeah but it's still an automatic transmission they're never gonna be light it's "

Coolant is the fluid that circulates through an engine to carry heat away and prevent overheating. The segment suggests they’re discussing what coolant is “right” for a particular setup, which matters because the wrong type or mixture can cause poor cooling or corrosion.

Term

check engine light

"...there's a whole thing before we couldn't get a sticker... because the check engine light burned out yeah..."

The check engine light is a warning light on the dashboard. If it’s on, the car is telling you something is wrong, and if it’s burned out you can miss the warning.

Part

O2 sensors

"...there was two boxes in the trunk of O2 sensors so I thought for sure there was going to be problem..."

O2 sensors help the car figure out how much fuel it needs by reading the exhaust. If they’re bad, the car can run poorly and fail emissions tests.

Term

fuel pressure

"...rather than like take the car apart and like see if the fuel pump will work or how much pressure are going out it was like the $35 we'll just buy a fuel pump so put a fuel pump in the car and the car still no start..."

Fuel pressure is how hard the car is pushing fuel to the engine. If it’s too low, the engine won’t get enough fuel to fire up.

Term

fuel pump

"...rather than like take the car apart and like see if the fuel pump will work or how much pressure are going out it was like the $35 we'll just buy a fuel pump so put a fuel pump in the car and the car still no start okay interesting it did have spark it did have fuel..."

The fuel pump is like the car’s fuel “water pressure.” If it’s not working, the engine can’t get the fuel it needs to start, even if other systems seem fine.

Term

crank sensor

"...on an engine spin down I'm like well the only thing left is the crank sensor order the crank sensor had a waiting to go started looking up how to do the crank sensor..."

The crankshaft position sensor (crank sensor) tells the ECU the crank’s rotational position and speed. It’s critical for engine timing; if it fails, many cars will crank but not start.

Term

factory service manual

"...had a waiting to go started looking up how to do the crank sensor which thank you Andrew for finding me the factory service manual online that helped a lot um figured all that out..."

A factory service manual is the manufacturer’s official repair guide with procedures, specifications, and wiring/diagnostic information. Using it helps ensure correct steps—especially for jobs like crank sensor replacement where timing and alignment matter.

Term

timing belt cover

"get the wheel off got the requires taking off the alternator belt the power steering belt the power steering bracket [510.2s] the timing belt cover and obviously the crank pulley as well had to go get a special tool"

The timing belt cover is like a shield over the timing belt. You take it off so you can see and work on the belt and timing marks.

Term

dowel holes

"they have a little carport at their house we'll push under the carport get in the shade [500.6s] and we'll start working on this thing so I fought with it for a bit you know get the wheel off got the requires taking off the alternator belt the power steering belt the power steering bracket [510.2s] the timing belt cover and obviously the crank pulley as well had to go get a special tool [526.3s] for taking the crank pulley off because obviously when you turn the crank pulley the whole engine spins which is fun of course Mitsubishi makes a special tool which you can't get but it seems that [542.1s] most modern cars and again Andrew you have more experience of modern cars than I do they have [547.5s] these little dowel holes on the crank pulley"

Dowel holes are small precision holes used to line things up. The special tool pins go into them so the engine doesn’t move while you’re loosening bolts.

Company

O'Reilly's

"the one on O'Reilly's was $89 but case the race around the cars apart the parts in stock we're [796.7s] gonna do it we're not waiting any longer"

O'Reilly's is an auto parts store. People use it to buy replacement parts quickly, especially when you need something the same day.

Company

Harbor Freight

"waiting for Naomi again kindly to go get [849.2s] the the tool from Harbor Freight and all those little things but it all in all it wasn't too [855.4s] bad of a job"

Harbor Freight sells tools for less money than most stores. If you’re doing a repair at home, it’s a common place to grab the one special tool you need.

Term

ECU

"there's not much left to change except for maybe the ECU so it is what it is but it's good to go"

The ECU is the car’s computer for the engine. It decides when to spark and inject fuel based on what sensors tell it.

Term

snow tires

"and it's either the snow tires are junk because they're five years old or it's gonna wheel bearing that needs to be replaced"

Snow tires are tires made to work better in winter. They can feel different from regular tires, so they might affect noises you hear while driving.

Term

summer tires

"I'll find out when I switch the summer tires in a couple weeks if it doesn't go away then yeah run to a wheel bearing"

Summer tires are made for warmer weather and don’t work the same way as winter tires. Swapping them can help tell whether the noise is caused by the tires or by something in the wheel.

Term

soft top

"...brand new tan soft top matching soft top frame complement the warm custom cream interior..."

A soft top is the fabric roof on a convertible. It can be replaced or refreshed, and it usually comes with a matching frame that supports it.

Company

Centerforce

"...new clutch and center force disc 10 inch wide front and 13 inch wide rear rims..."

Centerforce makes performance clutch parts. People buy them when they want a clutch that can handle spirited driving better than the original.

Part

wide fender flares

"...10 inch wide front and 13 inch wide rear rims to match the wide fender flares..."

Wide fender flares cover and protect the body while allowing wider tires and wheels. They’re often used for stance and clearance, especially on track-focused or heavily modified cars.

Term

vinyl top

"unmolested true blank with all original parts we'll need trunk pans rear quarter panels front fenders doors seem pretty good and vinyl top shows some bumps underneath getting rust details so hard top black vinyl top"

A vinyl top is a cosmetic roof covering that was popular on many classic cars. It’s also a clue for identifying trim and body style, and it can hide rust or water intrusion issues if it’s been neglected.

Term

rear quarter panels

"unmolested true blank with all original parts we'll need trunk pans rear quarter panels front fenders doors seem pretty good and vinyl top shows some bumps"

Rear quarter panels are the metal sections around the back wheels and rear sides. If they’re rusted or damaged, it can be a bigger job than it sounds.

Term

carb

"hard top black vinyl top 40 cubic inch motor four bell carb warwick blue interior with blue yeah warwick blue exterior with blue interior highway headlights"

A “carb” is the part that mixes fuel and air for the engine. On older cars it can need tuning or cleaning, especially if the car has been sitting.

Term

Rally II wheels

"power antenna rally two wheels uh that's about it i don't know if you can get it from that"

“Rally II” refers to a specific wheel design associated with Pontiac muscle cars. Wheel style is a common authenticity clue because certain wheel options were tied to particular trims and years.

Term

needs quarters needs floors needs rock

"but that's gonna be a nice garage find car and then it's like needs quarters needs floors needs rock it's like okay the second car looks really good running driving"

This is shorthand for major rust/bodywork areas: “quarters” (rear quarter panels), “floors” (floor pans), and “rock” (rockers—lower body panels). These are among the most expensive and labor-intensive rust repairs on classic cars.

Term

Firebird

"yeah the highway headlights was also the other clue that made it not a not a firebird but i mean a running driving gto"

Pontiac Firebird is another classic Pontiac model, and here it’s used as a comparison point for identification. The speaker says the headlight clue suggests it’s not a Firebird, reinforcing that the car is likely a GTO/Le Mans instead.

Company

Phoenix Corvette Center

"...you're welcome to stop in at our dealership phoenix corvette center and make an offer..."

This is the dealership name mentioned in the segment. It’s relevant because the seller is offering the car directly through that store, which can matter for how the listing is sourced and serviced.

Term

pop-up headlights

"[2328.2s] I'll give a few more hints it is front wheel drive okay twin carb front wheel drive five speed manual [2335.9s] pop-up headlights two plus two coupe configuration [2345.1s] uh"

Pop-up headlights are headlamps that pivot upward from the front of the car when activated, rather than being fixed in place. This design feature is often used to identify specific models/years and is a recognizable styling cue.

Car

Honda Prelude

"[2347.9s] all right is it it's Japanese it's not Japanese it is Japanese it is Japanese yeah [2356.4s] whoa okay yeah uh very very mainstream automaker it's uh [2367.0s] it's a Honda Prelude yeah after giving you all that info you did get it correct"

A Honda Prelude is a sporty Honda coupe. Here, they’re talking about a specific version of it—one with twin carburetors and front-wheel drive.

Concept

hybrid

"the new one is only available as a hybrid currently which isn't what the enthusiast wants but if you want to sell a personal coupe in 2026"

A hybrid uses a gas engine and an electric motor together. It’s often more efficient, but some car fans worry it won’t feel as “pure” as a gas-only performance car.

Concept

daily driver

"if I was looking for a simple daily driver and I had the budget for that kind of car I can't see why I wouldn't buy one for a daily"

A daily driver is the car you use most days for normal driving. The host is saying this Prelude could work for that role even without being a super fast car.

Term

146,000 miles

"this old Prelude ... this car is cool though 146,000 miles so it's not like a a low mile cream buff"

Mileage tells you how much the car has been driven. 146,000 miles usually means it’s been used a lot, so you should expect some wear and maintenance needs.

Brand

Virgil Exner

"so yeah I I'm a huge fan of anything Virgil Exner um super super cool each designer has like one period of designer that's like super iconic and like I said"

Virgil Exner was a famous car designer. His styling helped define what certain Chrysler cars looked like during a specific era, and enthusiasts remember that “signature” look.

Concept

oem

"all other components are matching and when needed replacement parts installed are oem this blank classic is straight bodied never in an accident"

OEM parts are the same type of parts the car originally used from the factory. The owner is saying that when they replaced things, they tried to keep it as close to original as possible.

Concept

original vin cowl tag intact

"original vin cowl tag intact yeah yeah photos from when it was stored and covered"

The VIN (vehicle identification number) is the car’s unique legal identifier. A “cowl tag” is a manufacturer label typically located on/near the cowl area that can include VIN and build information. Keeping these intact supports authenticity and helps verify the car’s history.

Concept

Darlington race

"...they went to darlington race apparently it was not an official throwback weekend..."

Darlington Raceway is a well-known NASCAR track. The speaker is talking about a NASCAR race that happened there.

Concept

Sebring

"how about sebring sebring was pretty cool 12 hours sebring i forgot about that i watched [3640.2s] last few hours"

Sebring is a famous long-distance race—12 hours. Because different types of race cars compete at the same time, the final laps can be especially intense.
