I love it.
Here is the Under the Hood Show podcast.
This is Under the Hood.
Welcome to the Under the Hood Show.
We are glad to have you with us.
Russ Evans is here to answer your automotive questions.
Thanks for joining us under the hood.
Shannon Nordstrom is here to do the same.
Welcome, hoodies.
Thanks for tuning in so we can help you tune up.
I'm Chris Carter here to answer your calls at 866-594-4150.
Got some calls coming in.
Let's get right to them.
We're going to go to Colorado and talk to Chad.
You're on the Under the Hood Show, Chad.
What can we do for you?
Hi guys, thanks for taking my call.
You bet.
I've honestly, long time listener and first time caller, I've been scared to call in,
but now that I know that Shannon purchased the Land Rover, I have some confidence here.
Well, I don't know that you should give you a lot of confidence, but Russ has helped
me figure out my old Land Rover, the 68 Series II that I bought.
The newer ones, they were always interesting.
Do you want to know where he takes it?
All right, so what kind of 01 Land Rover do you have?
So this one's an 01 Discovery, and I'm getting a lifter tick, and I'm going to give you
some background.
You know, this is the aluminum V8 that Buick made in the early 60s, and I rebuilt this
engine before I put it in 30,000 miles later, you know, new cam, new lifters, name brand,
American company cam and lifters, developed a little lifter tick 30,000 miles in.
So I went ahead and did a full oil system flush and changed the lifter out, worked great
for about 10,000 miles, and now I've got a lifter tick again.
So over the Christmas break, I did another oil flush, ordered a second new lifter, and
when I went in there, there were a couple questionable lifters, not real tight.
I did change the one that's ticking, and now probably 1,000 miles later, I have a tick
that's developed again.
So to give you some background, I put in a mechanical oil pressure gauge, and oil pressure is good.
I mean, even at 100-degree days air conditioning on in-traffic, the oil pressure will drop
to the lowest, the 18 psi, and just off idle, it's up to 25 plus, and typically is, you know,
38, 40 psi.
I run 1540 weight oil in it, and I have been since I rebuilt it, but I'm just, I'm kind
of at a loss.
I seem to have good oil pressure and I keep losing lifters, so I wanted to get your guys'
opinion, if you would, do you think I got a bad batch of lifters?
Well, you're very ambitious, I'll add that right now, you're extremely ambitious, good
for you.
Not good for you that you're having to tear this thing apart all the time.
Can I ask, I don't think with this frequency this is it, but what kind of oil are you putting
in there?
I use Rotella, Shell Rotella.
Okay.
And that's still got the, that's a solid cam and lifters in there, correct?
It is.
It is.
And I've been, I change the oil every 3,000 miles, and it's been Shell Rotella ever since
the rebuild.
Yeah, because I know we've run into some of the older engines that if you don't use
an oil with extra ZDDP in it, it can tear up.
That's required in that engine.
It can tear up the cams and the lifters pretty quick.
Yeah, that hat, you have to put a ZDDPAT additive in that engine every single time
you change the oil, or it will ruin the lifters in cam.
That's something that we're just going to say.
And you can absorb that and think about it, what your oil is and what the contents of that
oil is.
But I will say that in the industry of engine machining from the factory to the aftermarket
post COVID, there has been a chunk of time where the metal material that was used was
substandard because of many reasons.
And there has been a lot of failed lifters by just a lot of certain manufacturers, the
aftermarket.
We could pick up a couple of them, but definitely a thing.
So I don't know where they're getting these lifters from or what it is, but if they don't
get a good, pure quality steel that they start with to manufacture these parts,
it will show itself in the ability to last.
And the inconsistencies that are in the material will happen.
Now I don't want everybody to scare the death, but I'm just telling you this has happened.
And because a lot of material didn't get used, it got set aside, it got set outside,
it had to be reprocessed again.
There's just a lot of recycling and a lot of choices that were made when things were
in short supply and being made.
And it's kind of all shaken out eventually in the last couple of years.
Somewhere.
And unfortunately, it's in the last couple of years we've been seeing this kind of sort
itself out.
And we talked about this on the show, and not trying to say we told you so, but during
the COVID era, when everything was scrambling, you couldn't get parts, people were using
different manufacturers than they normally did.
There's a lot of things that didn't have the people there all the time because they
were in and out of their plants.
How can you keep a quality control in those environments?
Not going to say impossible, but you would have to have such resolve and such standard
in your manufacturing process, ISO this, ISO that, but you'd really have to have some resolve to say,
okay, I know this is the best product to use, but I can't get it.
Are we going to do nothing, or are we going to use this other product?
Yeah, and we run into, in any type of manufacturing, you run into things where
they're like, oh, this was a problem we found out seven years ago, and now it's coming to light
in whatever.
So we're in one of those where you don't necessarily connect those dots.
So those two things could be true at the same time.
And as you know, we've had this thing apart four times now.
There's not a wrong way to put that together that would cause the where.
I mean, there's nothing you could be doing wrong.
No, no.
If you did, if you would have done it wrong, you would have done it wrong once, not twice.
It usually happens.
The cam has very, very little wear, you know, you can just kind of see the wear pattern,
the lifters, you're not cupped at all.
They come out good.
It's just, they're not pumping up.
It's kind of embarrassing when I drop my boys off at school to pull up with a carpet ticket.
Tell them it's got Rhodes performance lifters.
I'm pretty sure everybody's looking at me.
There we go.
Back in the 80s, you know, we'd run those and you couldn't tell if it's like,
oh, you got a monster engine in that?
Yep.
That's why it's going.
Just need a converter in there and we're good to go.
He didn't know if it was supposed to be lifting like that.
You remember those Shannon?
Oh, yeah.
With those variable lifters, they would bleed down,
so they would change the duration and everything.
I tell you what, that, well, that's not helpful though.
I know, but I'm just trying to tell him the thing.
He asked for some things to look for.
Might be that the metal is bad.
That doesn't sound great.
Have they been warranting the lifters?
They have not been, but I haven't asked.
Yeah, you might ask them if they've been having some...
That's a good idea.
I mean, the manufacturer, they may or may not tell you the truth,
but the parts vendors know how many returns they've had.
They can, you know, the wholesaler, if they ask the wholesaler,
can look and see.
Looks like there's been a lot of returns on this.
Because you get a couple returns, people are doing something stupid.
But when there's a bunch of returns on something
and they all start having the same reason code.
Like when you're on Amazon and it says,
I don't think you're a large Chris.
AI, we see your camera.
Yeah.
So, I mean, that's something that I would definitely be asking.
And I don't know enough about if there's something else.
If there's a Land Rover expert out there about this engine
that sounds like he knows more than you, call us in
if there's something we're missing here.
But this is a pretty mechanical operation.
It shouldn't be doing that.
That's the old Buick engine.
Yeah, it shouldn't be doing that.
Those old Buick engines, they did tick a lot.
This is my, this is number seven Land Rover for me.
And I've got up to nine in the garage right now.
Oh my goodness.
Oh, you're the guy.
It's a problem.
And if you have that many, you also know who to ask.
Because you don't have that many of something
and not know who the other people are that are online.
Is that all that's in the garage?
Or are there other ones in there too
that aren't Land Rovers that are older?
No, I'm scared to say everything in the garage
is a Land Rover.
I've got an intake from a 72 up to a 16.
Well, he's definitely got some Berkley classics in there.
Either they call that a collector or a problem.
Yeah, but you've definitely got some Berkley 1 classics.
I don't know if the 01 Discovery is a Berkley 1 classic.
Do you drive that like every day when you get a chance
or is it seldom driven?
That one's my daily driver.
Okay, that's not a Berkley classic.
But the rest of that collection could fall into Berkley 1
classics for sure, which is a huge price savings.
Chad, thanks very much for the call.
We're going to put you back on.
Get your number.
So if someone else calls with the Land Rover question,
we can call you 866-594-4150.
That's the number to reach us here at the end of the hood show.
If you're obsessed with a car,
if you really like a make of car
and you want to get a bunch of them, Land Rovers are.
You don't want to do that.
There's a number of people that have done it.
They're definitely a cult following for the off road
prowess of them.
Everybody can plan what they want to plan.
You never know how long you're going to live.
We've recently had several friends, employees,
and things that have had major medical things
that you never would have expected come in early age.
But if I make it long enough to get where I want to be,
I'm not collecting cars now.
I've got just a couple.
But I'm not collecting them now because my plan
is save all these years and collect later.
It's not going to be more than one of any car.
There's different things I've had or that I'd like to grab
that aren't really expensive.
They're not Ferraris and crazy stuff.
It's like, hey, I want that.
I'd like to have an 87 Nissan hard-body truck,
a nice one.
I'd like to have one of those Toyota SR5s
like they had in Back to the Future, that nice.
You know, the 85.
Things like that.
Remember the Back to the Future truck at the Toyota Museum
that they redid to look like it?
Yes.
Yeah.
I want to hold on a second.
Russ, I'm going to put you in the isolation booth.
I'm going to shut off your mic and headphones for a second.
Sounds like a guy who hasn't started collecting cars yet.
Right?
I mean, that's what...
I take him at face value.
Oh, I think if he starts, that's how it happens, right?
I mean, you don't ever think I'll own a bunch of the same.
He's a guy that's like super frugal, though,
and he has been very conscientious to make sure
that he can save for what he wants to do later.
That's what I mean.
You're in the silent booth.
What's the button?
Once he starts, I don't think...
I think what happened...
He's going to get like the Mustang likes he wants.
He's got a little bit of an addictive personality
once he gets going.
And then he's going to find one that's more like the one he had.
Yeah.
Yeah, for sure.
Yeah, okay.
All right, you can come back now.
Yeah, you just never know.
Yep, you're right.
I will tell Chad that I spent way too much time
over New Year's and Christmas break fixing something
that I didn't want to take to the install shop
to have Russ and the guys do.
And our 06 Rover Sport that we've had for a long time
that I fixed up that had electrical problems from water
and I'm getting in through the sun roof.
My son-in-law jumped in it and with my daughter
to take it back up north to his family.
He had already driven there once with it.
It's a two and a half hour drive.
They got just down the block and it started flashing
all kinds of lights and problems.
And it just about didn't start.
And so I'm like, oh my gosh, what's going on here?
So they jumped in her sister's car and they went
because they had to get there for Christmas.
And so I started looking at it.
I thought for sure the battery just went to Pahoots
and it was low power and I'm measuring everything
with the battery.
I had the battery out and I think it did kill the battery,
but I got a new battery and I put it in
and I started it again and started doing
some of the same stuff.
And then the clue that made me figure out
was the smoke coming from the alternator
after I put the new battery in.
And so it's a 4.2 liter supercharged motor
and the alternator is on the bottom.
And so I looked on YouTube because I read,
I read the service stuff online.
I'm like, this looks like something I don't want to do.
But there was a gentleman of Eastern European descent
on YouTube that had a viewed like 20,000 viewed video
of how to get the alternator out
without tearing the whole front end apart.
And I followed that plan and I got it done.
Barely.
I got it done.
It just barely fits in there.
Got a few of them like that.
Yeah.
And but that was a case where if you followed
the service manual,
they wanted you to tear in the whole front
of the vehicle apart,
taking the coolers out.
It's got a fan with a reverse clutch nut on.
I didn't want to mess with any of that stuff,
but he showed how to get the wrenches in the right place
and how to reach the tensioner.
And I proudly got it done and it's being,
it's on two test drives now
and it's still holding together.
I'm worried about one bolt.
I'm not sure if I got it quite tight now
because I couldn't get a ding rich on it.
Find out.
Yeah.
You just gotta follow the smoke.
That's what they said.
But that was, that was my professional diagnosis
when it started to smoke with the new battery.
That was it.
That was it.
866-594-4150.
Let's talk to Dennis.
You're on the end of the hood show.
Dennis, what can we do for you?
Well, I accidentally hooked up my battery backwards
on my 98 Dodge 1500 Ram Laramy series.
And so I straightened them out and the truck starts
and it runs all right, but the dash is just going crazy.
And the ding is going off as I'm driving down the road.
But like I said, you know, the car,
the truck is running all right, but I got no gauges.
Well, you got, you could have one of a couple of things
happening if you're lucky, the gauges are just fried
and you don't have to get a new instrument cluster.
That's if he's lucky.
If he's lucky, the other thing could be that it has a
a short on one of the electronic modules because of the battery being hooked.
You're lucky it's a 98.
If that thing was like an old one or newer,
you'd be in real trouble because you could have fried
every module in the vehicle.
This happens a lot.
It's not uncommon, especially when you get a vehicle
that has two black battery cables.
And the only thing that identifies it is that one has a little
pigtail bolted to the fender and the other one doesn't
because you go, well, where are they?
Oh, whoops.
Or if you have what's even more common,
battery's dead.
You get the jump pack or jumper cables.
You go to hook them up and you clamp them
onto the wrong ones so they're backwards.
If the battery is already almost 100% dead,
let's say two or three volts,
if you put a battery with a running car at 14 volts
on there the correct, you know, the wrong direction
when the cars hooked to other ones were correct.
Yeah, it will try to charge that battery in reverse
and you can actually take a battery, drain it to zero,
charge it in reverse and reverse charge it
where it's positive negative negative is positive.
That that can happen too.
It's not a good battery anymore,
but yeah, it's it can happen.
It confused me because I hooked the battery up backwards
and I hit the key and the world over,
but it wouldn't start.
Right, it'll spend the starter in reverse.
The cables were wrong.
Yep.
Yeah, you'll hear the starter spin in reverse.
It just won't, the solenoid won't kick out.
And well, it can kick out,
but not turn the engine over because it's still a,
it's just a magnet.
It's a coil of wire that no matter which way
you put power to it, it's going to pull that thing out.
That's no good.
I would, I would hope that it's the dash
and that maybe you could pick up a dash assembly
in a self-service, you pull it, type yard,
complete.
It's a 98.
It's old enough that they're out there,
but it's not too old that you can't find it.
And that's not a problem that they've all been pulled out.
Right?
No, no, they don't think it was a,
if it was a Silverado truck, they might be gone,
but not in a RAM.
Yeah, the Rams, I don't know if we've ever put one in.
Is there any other,
there isn't any other online,
inline module on that that he could have fried
that would have been, no, because
down in a RAM.
Dennis, thanks very much for the call.
Good luck.
That's a bummer.
Yeah.
And like Russ said, if that was a newer vehicle
that was a full CAN bus network,
you know, where it was using low voltage,
going to the components,
and it's like a little computer network,
that kind of a shock on those systems
just goes all the way through.
Like lightning through them a lot of times.
Doesn't always, but it can really do some damage.
We've seen some vehicles that need a lot of parts.
Eight, six, five, nine, four,
four, one, five, oh, let's talk to Allen.
Do you have some help for us there, Allen?
Well, no, I have a question.
The guy was putting new lifters
on what I'm going to call a used cam,
the cam already in the engine.
No, he put a cam and lifters in it.
Brand new cam and lifters.
Yeah, he did put new cam and lifters in the first time.
Yeah.
Yeah, but then the second time
he was just putting lifters in
because he thought the cam still looked new
in a sense is how we took it.
But because I know what you're going to say,
if you don't keep those matched up.
Yeah, there's going to be a problem.
There's going to be a problem.
Yep.
Yeah, yeah.
Okay, well, see, that's what I heard too.
Yeah, and you know what?
And now that you said that, Allen,
now that you said that, he did say that first time
it went 30,000 miles.
And he made a point to mention
that he had carefully inspected the cam
that the cam looked new yet or looked good.
If there's no wear, it'd be fine.
It should be fine.
Typically what we've been trained is the same thing
you got told the old school is that,
well, I remember being down at Jerry Ross's machine shop
and they were taking that stuff out
when I was a kid watching it
and they were putting the lifters and the cam
and everything was lined up in trays
to keep it all lined up.
So it went back in the same place
and the towers went back on the same place
on any of the heads or the main bearings.
And you kept all those wear parts wearing
in the same place if you weren't going to replace it all new.
And so you're right on the money on the suggestion,
but I don't think that was the case here.
Alan, thanks very much for the call.

When I got my first specialty car,
I called up my agent
and had him put it under my regular auto policy
and had very minimal coverage,
even dropping coverage in the storage months
to keep the cost down.
That was before I met the professionals
at Berkeley One Classics.
I'm Shannon Nordstrom, host of the Under the Hood Show

Berkeley One Classics ensured me
with an agreed value policy.

They also show me that I could ensure my vehicle
for what it was really worth
and keep my coverage year-round and still save money.

did not cover my car
when it was stored in my garage for the winter.

Let's go to Pennsylvania and talk to Art.
You're on the Under the Hood Show.
Art, what can we do for you?
I have questions regarding a 2014 Dodge Grand Caravan 30th
anniversary edition.
The selector knob, I guess I want to say,
for the heat is no longer changing
from windshield, face, feet.
Are those electronic or vacuum?
It's all electronic.
100% electronic on that one.
Got a motor behind the dash
and the control in the dash
and wiring in between and that's it.
Okay, at times I think
when you shut off the vehicle and you sit in it,
I think I hear like, you know,
motors shutting down.
I don't know what they're for
if it's for that or not.
You will.
You'll hear like a creaking, you know,
creak, creak.
Weird noises when you shut it off.
That's your doors moving into position in there.
A lot of times it'll move to,
some cars move to outside air
so that when you close the doors,
it has a path for the air to go
for pressure-wise.
Other ones will go to the recirculation mode
when you shut it off,
just dependent on a lot of different things.
A lot of them default to defrost
in case it breaks while it's turned off.
It'll break in the defrost position
to clear the window for safety reasons.
But you'll hear creaks and clanks and crunks.
So if he's hearing what could be
the actuator noise when he shuts it off,
but his four of them,
so he's going to hear at least one of them.
Yeah, but if he's hearing noises.
At least two I know, but okay.
And it doesn't work.
That makes me nervous.
Right.
That's, I'm wondering,
can I get to that the kind of probe things?
You could get to it.
Yeah, put the dash still in it.
You should be able to access the front.
That motor's got a shaft going all the way through it.
And where the shaft goes through,
you can see the end of it
and see if it's turning when you move it.
And YouTube will show you which one's which.
And if it doesn't move
when you turn the dial on the dash,
you know that motor is 98%
it's the motor that usually fails on those,
the little electric actuator.
And our partner over at Dorman Products
carries that little item.
It's electric.
Yeah, that motor on the back side.
It's behind the dash.
Firewall.
Yeah, it's under the dash above the throttle.
Above the throttle pedals.
Well, it depends.
If you've got a dual zone,
you've got one on each side.
If you've got a single zone,
they're usually just on the driver's side.
Yeah, then you've got one on each side.
The mode is on the driver's side
that goes face foot floor and windshield.
And the heat for the driver's side
is on the driver's side.
The passenger side is where you'll find the
blend door for the temp.
And some vehicles have both the temp blend doors
on the passenger side.
But the mode door is almost always
on just the driver's side.
Both blends are working, thank goodness.
So I'm chasing something more
on the driver's side most likely.
Right.
You know, some vehicles,
they'll call us like with an F-150
and they'll say,
hey, my mode door doesn't work.
I'm like, great.
That's like $300 job or whatever.
It's not horrible.
A few hours we've got to take care of.
But they'll say, oh, my left temp motor doesn't work.
Oh, well, too bad it's not the other one
because one of them is two hours.
The other one is 12 hours
because you got to pull the seats,
the console, the dash, everything to get that one out.
Because they just short you by a half inch.
If they made the carpet and the floor a half inch lower
or the dash a half inch higher, which they could.
There's plenty of room.
I've had the cases apart.
They could have molded it shorter
so you could get it apart.
But that's not what they do.
They don't dig into that deep
to think about serviceability later.
Yeah, the first person who had to work on it said,
hey, engineers, you missed it here.
Oh, sorry, we're going to be using this stamping
for the next 10 years.
Will it last?
Will it make it out of warranty
and not cost us a bunch of money?
Yes, then don't change it.
All right, thanks very much for the call.
Good luck.
Well, those heater boxes nowadays,
they come to the assembly line pre-constructed
and they get set in by a robot arm
that guides them into the vehicle
and then humans finish attaching them
and doing that work.
Most vehicles, they have a design for repair,
but I just know there's parts
that they've not thought of that.
They're only thinking about whether it's going to make it.
Well, this is on the backside of that.
Well, that's the best place we could put it.
And they make this giant box
to go in most of these cars.
Big H-back box.
Huge.
But vintage air and others like them
can make a box a third of the size
with all the same features to work better.
It cools better.
It has more BTU.
It heats better.
More BTU there.
Never thought of that, right?
But it's a third of the size.
You know, they were this big.
Yeah.
With multi-zone.
I'm like, what are they thinking?
Whatever.
866-594-4150.
I got a couple of questions on chat here.
One of these I thought was a very good question.
And we talked about it recently, I believe.
I don't remember the answer though,
but I think we asked this question on the chat.
Why does it seem that the newer cars
go through rear brakes faster now?
I've had two cars that I replaced the rear twice
before the front.
And so have my parents.
Two cars, same thing.
We just talked about this.
Did we not?
That should not be happening.
Was it the opposite?
Did we talk about it?
It's the opposite,
because a car does most of its stopping on the front
because the weight transfers to the front
as you hit those brakes puts pressure on the front wheels.
If you had more pressure on the rear,
even by a few percentage,
when the weight transferred to the front,
you would slide those back wheels.
And if you've ever had rear wheels slide,
that's because that's the problem.
Your front brakes are worn out.
Your back ones are dragging.
If you were to drive in reverse,
it would be opposite.
So yes, you should be wearing out the front,
typically almost twice as fast.
As the rear brakes.
Because...
And they're doing the opposite.
Yeah.
And so something is not right.
And certain cars have issues with rear brakes,
caliper sticking, hardware that gets rusty.
They just need to be serviced more often.
They can be every couple years,
they might need to come apart,
be clean and adjusted, things like that.
