Live from the Car Care Studios, it's the CNC Auto Show with your personal on-air and online automotive service advisors, Aaron Clements and John Ryan Mooney. So climb in, buckle up, and enjoy the ride on the CNC Auto Show. Welcome to the CNC Auto Show.
If you're looking for information on ways to make your car safe, dependable, and long lasting, you have come to the right place, especially if you want to have some fun doing it. So don't even twitch an eyebrow because we are ready to roll. I'm your host, Aaron Clements. Michael Rivers of Bo's Machine Shop is riding with us today. Michael, welcome to the show. Welcome.
Glad to be here. Michael is here not only to answer machine shop questions, but Michael is very knowledgeable in the automotive field in general. So just about any other question you have, we'll join together and answer that question because that's why we're here. Whether you're a do-it-yourselfer or a professional automotive technician, sooner or later you will need a good machine shop. And I don't care how well you clean a surface or how closely you go through the torque procedure, if a component does not have the correct surface or if it's warped, it's going to fail. Yes, amen. Or leak or whatever is involved there.
Absolutely. A few extra dollars of prep work can ultimately be cheaper in the long run and not only expense wise, but in your time and effort. I see a lot of people try to pull a head off and change a gasket and go right back. And they're calling me the next day, you know, saying what I do wrong.
And they didn't really do anything wrong. They just didn't check what they needed to check and have it machined like they should have. Because all of that is very important on making a good long lasting job.
So you be able to ask questions about things like the surfaces that you would put on the head, what's involved in head jobs. As a matter of fact, I'll be asking Michael a lot of those questions as we go. So if you do have a question about your car, truck, SUV, or machine shop work, surfacing, valve jobs, whatever, give us a call 800-224-9090 or 706-8635-800.
That's Saturday mornings, 805 to 10 Eastern time. And I want to remind you that you can watch us live on Facebook or you can go to ccautoshow.com and watch us and we are right there for you. And Michael, do you realize that last week we did not get an answer to our tech tip quiz?
That's terrible. To I think the second hour tech tip quiz. And so we had to bring it back. Okay. It's a rerun. All right.
Not really a rerun. It's just an unanswered question. So this is someone's chance to be in the Hall of Fame, Detective Quiz Hall of Fame. Sure. And receive a prize package, which includes a coffee mug with the official tech tip quiz winner. And not everybody gets to see that cup. I know. I hear those cups are highly sought after. Yeah.
I see them on eBay quite often. Okay. Here's the question. Bill was driving down a straight road. There was no police on the side of the road and there was no police behind him. So he let his car unwind a little bit and he still got a ticket.
How did he get a ticket? And so if someone's got the answer to that part, give us a call and we will also start discussing a little bit about cylinder heads. What do what does some items like cylinder heads, why do they need to be resurfaced?
What are some of the things that happened to them over time? Well, the majority of today's gaskets require much finer, slicker finish. And when you pull them off, you know, there's there's normally a reason why it's pulled off. You know, of course, some of your vehicles now you pull the heads off to do things like, say, get a manifold bolt that's broke off out or some engines you got to pull the head off to get the lifters. But, you know, it's almost always better to have it surface before you go back on. Just, you know, of course, there's there's some guys that, you know, they try to do it theirself. But, you know, like I said, the finish that we put on the heads today just can't be replicated by by hand tools.
Yeah, it looks it's not really like a mirror, but it's a much, much finer finish that I see. And and also they have the warpage that goes with that if a cylinder head's warped and you put it back on. I don't care how well you torque that thing. It's still not going to seal. Yes, sir.
You know, the war pages is funny. It's, you know, I like to think that if you get the head absolutely perfect, that way, if there's any distortion in the block or anything like that, the gasket can absorb it. Whereas if you got a little distortion in the block and a little distortion in the head, you know, it it calls a failure. Not only that, you know, you can it's hard to check, you know, for warpage, you know, say eight thousands in the end might not be that big a deal, but a couple thousands over a two inch span.
You know, that'll definitely create a failure. So and of course, the thing that we're trying to do here now, I realize a lot of people enjoy working on their own car. Some some people do it to save to save money.
But there's some people that just plain they have classic cars, they have different vehicles. And what we want to do during this show is let people know things that they can do to make it if they are working on it themselves, they can still have a good, successful job. But also to understand, like if somebody takes their car into a repair facility and has it repaired, if somebody says we had to take the heads to the machine shop, that that person will know why.
And that's what it's all about is knowledge. Michael, you ready? Let's go to the cause. I'm ready. Let's go. Here we go. Let's go to William. William, welcome to the CNC auto show.
And what can we help you with? Yes. Oh, you're here to answer. Oh, you know what we're gonna need to do, William. We are put you on stage. Yes, sir.
I'm prepared. William, you are on stage and what is the answer to today's tech tip quiz? Well, I've already guessed everything else, but, um, at this point I'm thinking he was like on a toll road where they struck you and you have a certain amount of time. You're not supposed to speed. You're talking about he was going through the toll booth thing and they took a picture of him? Oh, no, sir. No, sir.
That was the picture was last week. I mean, like there's a road you cut through SRS and they kind of like time you. They're too quick. They knew you were speeding. Yeah.
They timed him from point A to point B and, and, and he was bad. Well, in some ways, I can almost picture it in some ways that that could be right. But, oh, we have, I was trying to break the news to you before they, they, uh, gave you the, uh, button there, but it, that's just not it.
But in some ways you're on the right track. Well, uh, talking about the head, when I was back in college in 1982, we put a, uh, up in Charlotte, we put a head gasket on my buddies, my roommates, little Subaru. And of course, everybody in the world told us it was perfect. It was perfect. It was fine. We had it good. Yeah. We put that head back on there without it getting machined.
And, uh, we didn't make it to Rock Hill on the way home before it let go. You know, you can't look at it until, and so many times even checking it with a straight edge, it's hard to find that one little low spot. They all put a straight edge on it. Oh, it's perfect.
Even the instructor. Yeah. Yeah. It's good. It's good.
It's good. I watched Bo when he puts them on the machine to resurface them. And of course you can use a straight edge to get an idea, but once he puts it on that piece of equipment, then he can actually look at it and see how much of it, uh, is flat now.
And how much of it is not flat. Right. He knows how far to go. You take like a one thousands cut and you come back and you look at all the low spots and you're like, my God, you know, it could have failed in any number of places, you know? So it's, uh, it's, it's important, you know, and there again, you know, a little extra energy and effort, you know, makes up for us.
Well, it's, it's also, like you said, the instructor's like, oh, don't worry about it. That's a thick gasket. That's a thick gasket. Yeah.
It'd be fine, but it was an aluminum head too that had been run hot. Wow. Yeah. So nowadays you looking back on it, you know, it was, yeah, no doubt. Well, we really appreciate you sharing that with us and letting others know the importance of having the machine shop work done when you do. And when you do a job, we'll appreciate that. Take care.
You too. Okay. Let's pull over for right now. I need to run inside for a moment, but when I return Michael Rivers and we will be ready to answer your automotive questions.

We are ready to go to some more callers and it looks like within just a few seconds here, Billy was next. Billy, welcome to the CNC Auto Show and what can we help you with today? I got two questions and I'm going to try to take two quizzes. All right, man. This sounds perfect.
I love it. What are they? The actuator motor on a 2008 Chevy Express van.
How hard is it to get to it? Which one? You have several actuator motors. You have the temp door actuator, the recirculate door actuator and the mode door actuator. I need the one that makes the air condition blow out. It only comes out of my deep frosting.
Sounds like you need a mode door actuator. And what year model is that one again? 2008.
2008. Okay, now I'm going to have to go from memory. I think that the mode door actuator, if I'm not mistaken, is accessible without having to pull the whole dash out. You got to be a contortionist to be able to do it.
I bet you do. But if I'm not mistaken, the temp door one, and I hope I don't have those mixed up, but I believe the temp door one, you do have to. But the next step, what we normally do, would be to look that up. If a technician was looking at it in a labor guide. So we have guides that give us a rough idea how much time it takes to do things. And if you look up mode door actuator and you see kind of a small hourly number, then you don't have to pull the dash out. If you see a large hourly number, then you do.
And of course, that hourly number relates to dollars. Now, while we own actuator motors, I got a 93 Chevy pickup and the actuator motor went out on it and I got it in. And do you know anybody that installs custom dashboards? Well, I can tell you now there's some great up upholstery shops here. Of course, Redmond upholstery here.
And of course, in different cities that people are listening to this show at, there's normally always some real good upholstery shops in the area so you can get that done. I will tell you though, I don't know how fine looking you want it, but they make some pretty nice little dash covers now to where you can actually, I think it just kind of glues on top of the old one. It's real thin. So that's something to think about.
I got one of those. Oh, you do? Okay.
Yeah, but I might have to have some plastic welding done first. Oh, okay. Well, keep listening to the show because we got a great surprise. We have, during the show on the second hour, we have Chip Hansen. He's going to be joining us and he's the president, chairman, and CEO of J.B. Weld. And he's going to be joining the show. And you never know, J.B. Weld just might solve all your problems. Or is it too far gone for J.B. Weld, Billy? No, no, no, no.
It's just one piece that's broke off where the glove box closes, that little piece that holds the roller on. Oh, wow. We may have the answer for you, so keep listening.
All right, let me try the tech tip quiz. You know we need to put you on stage, though. Yes, sir.
That's blue. And he comes in really early to get ready for that. He sits there in front of the mirror with his, getting his lips all puffed up and ready and all that and his bugle clean. All right, Billy. Sounds like he's been practicing with the guy at Churchill Downs. Yeah, yeah, no doubt.
Now, we're going to, I'm going to need to read the question real quick. Bill was driving down a straight road. There was no police on the sided road or the road behind him. So he let his car unwind a little bit. He still got a ticket. How did he get a ticket?
And Billy, all eyes on you. What is the answer? He got a camera ticket. A camera ticket. Oh, so he was just... The camera clogged him and took a picture of his tag and then sent him the ticket in the mail.
You know, that's not a bad, bad answer. I mean, because it is, it is a possibility that because of an actual police not being on the sided road, it was a camera on the sided road. But I would almost classify that as the police.
I mean, if you, I mean, if they're sitting there taking pictures of you. Yeah. So, so that, that means... Give me the oohs and aahs then. Yeah. Oh, no. Okay. There you go. Yeah. All right.
And some people have a hard time with that, but you took it great, Billy. Thank you. Thank you, man. All right. Bye bye. Bye bye. Okay. Number to call, 706-863-5800.
We have a question about your car, truck or SUV. You just give us a call. And we were, uh, we were talking to Michael, uh, mainly about surf, uh, uh, cylinder heads in the beginning. And we got about, we wouldn't have time for another caller right away. So I'll go ahead and ask this question.
We got about a minute. The, um, what does it, what does it mean to pressure test a cylinder head? Pressure test and cylinder heads, we're, we're looking for coolant loss. You know, you, you actually, you block all the coolant passages off and you pressurize the coolant system and you spray it and you look for leaks or, you know, it could be a pinhole. It could be a crack.
It could be, you know, you check it similar, like you would check for a flat tire, you know, and, uh, if you're, yeah. So you put the pressure on it, then you dunk it under water. And if you see bubbles, you gotta, you gotta leave. Right. We use a spray solution.
We don't actually dunk them under water. Okay. So, you know, if you got unexplained coolant loss, that's, that's where you need to go. Yeah.
And we get a lot of our pressure tests just in case you don't want to put it on the car. All right. Wait right here. We have Michael Rivers in the car with us ready to answer machine shop questions or any other automotive question. If it's Saturday mornings between the hours of 805 and 10, you can be dialing 800-224-9090 or 7 0 6 8 6 3 5 800. We'll be right back.
It's time for more good stuff with Aaron Clements and John Ryan Mooney. The CNC auto show is brought to you in part by K seal ultimate.

K seal it. I am back with you along with Michael rivers, ready to answer machine shop questions or any other automotive question you might have. All you have to do is dial 800-224-9090 or 7 0 6 8 6 3 5 800. And that's Saturday mornings, 805 to 10 Eastern time. And you can also watch the show on Facebook and we will go straight to Jim. Jim, welcome to the CNC auto show.
What can we help with? I'd like to talk about retrofit air conditioning of the R134. I'd also like to talk about, I'm the same car, a transmission engagement sensation. And I have an inability to factor in with apparently an Aaron factor in that tech tip quiz. Oh, okay.
But I have a little idea about the tech tip quiz, but I can't quite put it all together. So I'll tell you what I think and take a fog horn or an all button, whatever. And then we'll talk about the car, whatever you want to do.
Absolutely. Well, we'll go with that, but are you going, Jim, a lot of people have to rest for a few minutes after, if you happen to get the all button. And of course, if you get the, if you get it right, then you're going to be so excited.
You're not going to hardly be able to talk. So let's do the car questions first. I'm ready for the first one. It's a 1986 Monte Carlo Super Sport, which has, I believe, a high output engine in it and four speed automatic transmission.
Whoa, I love it. Let's talk about the trans part. And I haven't had, and I've just gotten the car recently, and I haven't had one of this vintage in a really long time. And I've only moved it a little bit because I don't have it registered and insured yet. But I've noticed that when I put it in drive or park, I'm sorry, in drive or reverse when parked, that it seems like it really just, it's a harsh, almost a bang in the gear. Like the vehicle doesn't do like my later models where you can hardly sense it at all. Is there something about that vintage that would indicate why that would do that?
Or would that be normal? And tell me the year model of the Monte Carlo again. 1986, five liter V8, four speed automatic. Okay. Now, that model has a carburetor then, right? It does. Okay. And I find that that might have been the year where they had computerized carburetors.
And I remember them very well. But Jim, what you run into with the models with the carburetors is without having the computer to compensate the speed like they do now. Like on a modern car, when a person puts it in drive, the computer senses that you're putting it in drive. So it automatically raises the idle speed so it would accept the load of the air condition. And if it didn't, then the engine would bog down.
So the only way they could do that in cars with carburetors, they would have a solenoid on the side that that solenoid is supposed to kick up and hold the… It would kick up the idle speed when it was time to…when you did cut the AC on. And so it just was not as smooth. It wouldn't react as good. It would get out of adjustment to where they wouldn't go up high enough. So many times, people would have to compensate with that with idle speed. So they would bump the idle up a little bit. And then that would make it to where when you put it in drive, you would have a heavier bump. So I would check the idle first. If it's sitting there around 850 or 9, I would adjust it down just a little bit and hit that just right spot. You'll find a little flathead screw on the driver's side of the carburetor that you can stick a screwdriver. You've got to use a skinny screwdriver. And then idle the RPM down just a touch and see if that makes it go away.
But even when you do that, it's not going to be as soft and smooth as a lot of the modern cars because of the way the torque converter is designed. Michael, does that sound mostly correct? I was thinking idle speed. You know, that's what it sounds like to me too.
Yeah. And it might be a tuning issue. I have a service manual for it and it talks about engine idle speed as I was along those lines myself.
And let me tell you a little bit about what you see on the landscape there. It does have the mechanical screw right on the body of the carburetor up by the primary intake circuits that is like a base idle adjustment. But away from the carburetor and separate from the carburetor on a flange is an electrically connected and apparently adjustable idle speed controller which has a very large hex head on it.
You can adjust that so I was wondering based upon your knowledge of the car, is that for just an air conditioning adjustment or is that a computer controlled idle device for all events on the engine, would you know? Well, they use that solenoid for two different reasons. One is sometimes they would use it for the air condition to make it to where once you cut the AC on, that solenoid would activate and move the RPMs up just a little bit to make it to where it would still idle well even with the AC on. But now that I'm thinking about it, that model may have had more of an anti-diesel solenoid to where any time the key is on, that solenoid is what holds the RPM up a little bit higher than the base RPM. And the reason they did that is those cars used to diesel really bad.
You'd cut them off and they'd sit there and run for like a minute after you cut the car off. And so to solve that issue, they held the idle speed up with that electrically controlled solenoid. And when you cut the key off, that electrical current would go away from the solenoid, RPMs would drop down to like 450, 500 RPMs, and then the engine would shut off because of low RPMs and wouldn't diesel so bad.
Gotcha. So I need to go through the key cycles and look for what circumstances activate that solenoid. Is it key on?
Is it AC on or both? I would go to, you can go to the internet to get this information and get the idle adjustment procedure. And when you look at that, it'll tell you how to adjust that solenoid that's on the side because that's what's going to make the difference on how you do it. And it might say disconnect electrical wire, idle it down to say 600 and then plug it back up and activate the solenoid and then move that screw up to 850 RPMs. And that makes it to where when you cut the key off, boom, it'll drop down to the lower RPM and cut the key off. If it's the other type, it would let you know in that procedure which way to do it if it's only used for the AC.
But I think that was called an anti-diesel solenoid. Yeah. Okay. Okay. All right. Next one. Looks like, yep, looks like it's got R12 in it from that vintage based on my research.
Would you agree? Yes, more than likely did. Okay. And it's blowing no cold air, but we did jump the low pressure switch for just an instant, compressor in, nice and quiet, just connected it just so we know that it spins and it's quiet. Can you tell me a little bit, since I've never done it or had it done rather, the conversion to R134A? I know there's fittings. Are the fittings have to be soldered in? Do they just affix themselves to the existing fittings? And just what's the expectation in the process for that conversion?
Yeah, they're pretty quick. In the beginning, when they first converted over to R134A, they were saying we had to take the evaporator off and take the compressor off, empty all the old oil, put the new oil, I mean, it was a very expensive procedure. But in time, people found that in a lot of cases, you can just put the fittings on, put a vacuum on the system and put it in there, because if the compressor goes, they were saying that the compressor would go bad if you didn't. Well, if the compressor goes bad, replace it with one that's compatible with R134A, and instead of spending all that time and effort doing it other ways. And then in doing that, you pretty much just put the fittings on, put a vacuum on the system. We always like to leak check it, but do that and then put the R134A in and you put a little bit less R134A in than you would as far as R12.
I think it's something like 10% if I remember right, slightly less. But Jim, we're going to need to go to a real quick break and we will, when we return, we'll be looking for the answer to the Tech Tip quiz. We'll be right back.

That's on Saturday mornings, 805 to 10 Eastern, and we have Jim on the line. He had a couple of questions earlier, but he has told us that he has the answer to the Tech Tip quiz. Jim, is that true?
Let me try this again. Jim. Yes, sir. Okay. Now, you had asked, did you have any other questions that you were asking before answering the Tech Tip quiz?
Nope. I can take what you told me before and go apply that information and then we'll go from there. So thanks for that.
That is perfect. Did I hear you right that you have the answer to the Tech Tip quiz? Well, I've got maybe a direction I'd like to take with it.
Whether I can answer it all, I don't know, because I'm having trouble calibrating what might be, as I said before, the errand factor. You're very, very tricky with these things sometimes, Mr. Clements. We add a few little things in there.
Do you know one reason for that, Jim? What I did, and I'm going to post this on the CNC Auto Show page, but Mason, our producer in there, in his studio part, he now has a lighted palm tree, and we call that, we do that for, it's a thought-provoking type lighted palm tree. So you'll just sit there and look at it and ideas will just start popping into your head. It's really kind of neat.
I think I need one of them. All right. Now, we're going to put you on stage. Jim, what, well, here's the question. Bill was driving down a straight road. There was no police on the side of the road or behind him. So he let his car unwind a little bit. He still got a ticket. How did he get a ticket?
And, Jim, what is the answer to the day's Tech Tip quiz? I don't know all the rules and the parameters, but it sounds like this straight road might be a drag strip. Somehow, if you do something right, or if you do something wrong, your next step is a ticket. Maybe a ticket is a time slip that all drag racers get, or he did something else.
Oh, wow. You added a twist in there, Jim, that I wasn't expecting, because I was planning to ask you how you can get a ticket on a drag strip. But you're saying a ticket, the ticket was not a police ticket.
It was the ticket of your time that you ran at the strip. Yes, something of that nature. Wow. That was good. That was really good. And, Jim, you very seldom get that now.
That's really rare for you. As we said before, some days you're the bug, some days you're the windshield. Today, I'm the bug. Jim, thank you very much. You bet. Thank you, Paul. Appreciate the call. Thank you.
Okay, the number to call is 706-863-5800. Michael, who do you think we should – oh, here we go. I think we should go Tilden. Tilden's next. Let's go to Tilden.
Hey, Tilden, welcome to the C&C Auto Show, and what can we help you with? Oh, Tilden. Oh, Tilden must have – I hope Tilden wasn't driving.
I hope he falls back. And that phone call stopped like that. He was waiting for a while. Yeah, that ended so suddenly. I'm just hoping he wasn't driving and talking.
Yeah, it sounded like a little background noise there. Well, why don't we go over to – why don't we take this on to Curtis and hope that Tilden's okay. Hey, Curtis, welcome to the C&C Auto Show. Good morning, guys. How are you all? We are doing good.
Good. And I'm glad you're okay, but I'm kind of wondering about Tilden now. Tilden will be all right.
Yeah, I hope so. What can we help you with? I want to try to answer the – Curtis, you didn't sound real concerned about Tilden to me.
Yeah, you didn't sound very concerned at all. No, uh-uh. We got the competition out of the way. All right, well, he'll be okay. All right, now – oh, so competition, that means that you may have an answer to our Tech Tip quiz. That's right. All right, well, we're going to put you on stage.
And, Curtis, we're going to listen as you just snatch it away from Tilden. What is the answer to today's Tech Tip quiz? I know you go to some states and everything, and you enter in, they say we're going to monitor by aircraft. Uh-huh. And I didn't know if he may have got a ticket – Oh, wow.
By highway patrol, you know, who was in our aircraft. We're getting some really good twists on this that I didn't even think about because some of those could have been good answers. I mean, the answer, but that, of course, was not the answer. But, Curtis, you very much tried to take that away from Tilden but didn't quite do it.
And Tilden hadn't called back yet, so it might not be good. So, Curtis, thank you. Thank you. Appreciate the call very much.
Okay, the number to call is 706-863-5800. We'll move on over here to – let's go to Lewis. Lewis, welcome to the CNC Auto Show, and what can we help you with? Hello, Lewis.
I'm going to try one more time. Lewis, welcome to the CNC Auto Show. All right, we don't – Tilden's back. Tilden's back. Let's go back to Tilden.
Let's see here. Tilden, welcome to the CNC Auto Show. Hello, can you hear me? Yeah, are you okay? You were – we heard you very briefly before, and I was worried that you was in some kind of accident. No, no, I'm not driving. Technical difficulties with a Bluetooth. Yeah, it always worries you if you're talking to somebody on the phone and boom, it just stops.
You say – and they're in the car or something. It worries you very much. Okay, all right, now, what can we help you with?
I'd like to try the tech tip quiz. Oh, my goodness. There is no try.
There is do, only do. Okay, we're going to put you on stage. Bill was driving down a straight road. There was no police on the side of the road or behind him, so he let his car unwind a little bit. He got a ticket.
How did he get a ticket, and what is the answer to today's tech tip quiz? Well, actually, I had a friend who worked for South Carolina DOT, and one of his jobs was to paint white stripes on the interstate at a certain interval, and DOT had either a plane or a helicopter, and they could time people from the air to go from one strike to the other. So the police weren't on the side of the road.
They weren't behind him, but they were above him, and they could just monitor it. But you know, I always wondered about that. When they do that, how is the plane going to pull you over? Oh, they just mail you a ticket. I would have to assume that they would have a policeman, a highway patrol, waiting somewhere up ahead for whomever this is.
I hope so, because I wouldn't want to be riding down the road and look over to my right and see an airplane beside me with the man inside the airplane saying, pull over. That just wouldn't be good. That's not a good thing. Man, I am so sorry. Good shot, though. All right. Thank you.
Bye-bye. Okay, we will ask another machine shop question, because we only have one minute, and as soon as we return, though, we'll be going to John. So on the question here, Michael, what causes an engine to use oil?
We've got a minute. That could be, you know, multiple things, just wear in the cylinders, bow stem seals getting old and tough, hard. I don't tear down that many engines, but I've had cases to where I've strongly suspected that the oil ring was stuck. Sure, sure. Do you see that a fair amount? Well, more so than ever. Now, your newer engines are using less tension rings, and, you know, with less tension, it's easier for them to clog up and whatnot, so that's the real deal. Plus, today's fuel isn't as good as, you know, it has been in the past, and people not changing oil and whatnot. Oh, this is way out of time. We'll be back with the next hour shortly.
