Failed inspection! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Mike Culpepper · 06-13-2005, 09:40 AM

Did the stock air cleaners on these trucks have a heat riser that comes off exaust manifold? I failed inspection the other day and the guy said it was coz the ait cleaner was made to have a heat riser and my truck doesn't have one.
Do you think I could just get an aftermarket chrome air cleaner and put it on and it would pas then?
THis truck passed last year withsame set up????

I have the same thing missing, but the inspection guy just told me to fix it and gave me a sticker anyway (never did it, though. don't know where to get the hose). Do you have a hole on top of your driver side exhaust manifold? That's where the hose plugs in.

whitesswj · 06-13-2005, 10:01 AM

So long as you take the apperatus off of the exhaust manifold or you could just go to autozone and get some Heat Pipe for that purpose.

Mike Culpepper · 06-13-2005, 10:21 AM

My exaust manifold does NOT have plumbing for the heat riser, it is smooth on the top of the manifold. Does anyone have pics of the manifold part of the heat riser? It has 4 holes on the side of the exaust manifold that are plugged.
Alot of y'all have chrome air cleaners, do y'all have trouble at inspection time?

jtminton · 06-13-2005, 10:24 AM

I don't have any close up pictures, and I don't have my truck here at work. It's about a two inch hole right on top of the front half of the driver side manifold, if that helps.

Mike Culpepper · 06-13-2005, 10:40 AM

Just double checked mine, nothing like that on my manifolds. Which is correct for '72, the air cleaner or the manifolds? I'm hoping I don't have to get different manifolds!

farside847 · 06-13-2005, 10:45 AM

There is actually a metal shield that bolts on top of the driver side manifold that
has the attachemnt for the heat pipe. The hole is not on the manifold itself. Im
sure someone will post a pic, if not I will get one tonight.

Ah, found a pic here:

Alex Hayley · 06-13-2005, 10:58 AM

I had the same problem. Just get some heat pipe from a autoparts store, and slip it on the airfilter housing and have the other end resting on the exhaust manifold. It will pass then.

jtminton · 06-13-2005, 11:00 AM

It's the stock manifolds and air cleaner on my 72 C-20.

Mike Culpepper · 06-13-2005, 11:32 AM

thanks for the replies, I guess I'll go to the parts board and look for the heat shield/riser thing.

jtminton · 06-13-2005, 11:35 AM

You could also try another inspection place. I got mine done at one of those quik lube places full of 18 year old kids. Like I said before, they just told me to fix it and gave me a sticker anyway.

Mike Culpepper · 06-13-2005, 11:52 AM

Thats a good idea, I think I may try that first. Thanks for the help.
Mike

GMC AMI · 06-13-2005, 11:59 AM

Not all inspection shops are that picky or pricky, LOL. Put a chrome one on and try another place, must be a million where you live in the state of Texas.

I've (luckily) never failed inspection. Do you still have to pay the $12.50 if you fail?

**VetteVet** · 06-13-2005, 12:58 PM

Here is one off a 1971 I saw on e-bay.

71-longbed · 06-13-2005, 01:33 PM

what does that have to do with the price of tea in china ..... why would the inspector care if your hot air tube is still on the truck ?? im glad i dont have to do that junk

TruckinDaddy · 06-13-2005, 01:54 PM

Yep, you gotta pay, pass or fail in Texas.

Some states require emissions inspections on all vehicles. The heat riser is a critical part of the startup/warmup. In California as in most states even though we don't have to inspect any vehicle 30 years plus we are still required to have the emissions equipment that the vehicle was sold with. The other day one of the members from So Cal mentioned they were doing roadside checks again. They can check any vehicle without regard to the year. In 1982 I failed emissions testing on a1976 Blazer because I had the top of the air cleaner turned upside down to let fresh (hot, duh) air in. I had to repair the air cleaner and start the process over again. Yes I had to pay for another inspection. California laws can suck at times.

71-longbed · 06-13-2005, 02:08 PM

that sucks .... another reason to stay in Oregon

mocwon · 06-13-2005, 02:30 PM

I'd take it somewhere else for the inspection. When I get mine done this ought to be interesting given the fact that the whole induction system has been replaced with a TPI system. I think I'm going with Texas antique plates to avoid the entire inspection process.....

That was what I thought, and I argued that this was a safety inspection only! He said that if the vehicle was supposed to have the equipment when it was sold , it should still have it to pass. He also implied that if my engine was newer than '85 it should have catalytic converters(I'm pretty sure he knew my engine is a new GM crate engine, and mentioned the catalytic c**p to get me to shut up). SOOOOOOO, I shut up and wrote a check for $12.50, and left. I didn't mention he also failed me coz my high beam indicator light, ( in the dash), was out and the license plate light lens was cracked!
I'm new to the area where I'm living now and will take some time to learn where NOT to go for stuff like this.

It's that way in Oregon, too, where there are inspection stations and the roads are paved.

flip66 · 06-13-2005, 06:32 PM

where did you take it I have an open air cleaner on mine and it passed in dallas. The place I take it does not even raise the hood

Hutch · 06-13-2005, 07:08 PM

Mike,
Change the air cleaner to aftermarket and take it to an inspection station where the majority of there business is inspections.

Also show up just before closing time.
You will want to be the last inspection of the day.

The part that installs around the manifold is a heat stove and it is a 2 part item.
They are kind of rare because they rust and and tend to self destruct due to the heat.
Most folks do away with them except the ones doing an original restore.

Jwill41 · 06-13-2005, 09:00 PM

I have a chrome cleaner on mine that is open. I was told that it had to be enclosed but passed anyway. The same inspector told me I did not need a high beam indicator but that cant be right. I have always had good luck I guess, but they just dont seem too picky on these trucks to me.
