what year and motor do you have?

 

its a 1988 rs 305

 

i ripped a 3 inch exhaust off my 85 camaro 350 carb but it had no air control on the headers so its gone on my 88 rs now just wanted to no if that would my engine light off ?

 

unplug the electrical connecter on the A.I.R. diverter valve. to see if a check engine light comes on

 

I THINK it does if you remove the egr, but my light didn't come on when I removed the a.i.r. system.

 

I have had mine removed for a while and no check engine light

 

I know im probably beating a dead horse but I got a 84 camaro with the A.I.R system partially gone and the tubes off the exhaust manifold were rotted so I plugged it up. Does anyone have pics and/or instructions for the whole removal process? Im trying to get the car running again. Any help would be greatly appreciated.

 

You need a catalytic converter without the air tube on the side first off, then you just start unbolting stuff, you're also going to want a smog pump delete pulley otherwise the pump will seize and shred your belt.

 

Yeah, I ripped all that stuff out for maintenance

Sounds sick!!!!!

I don't have a serpentine. I need the vacuum diagrame for the complete job with out smog pump if anyone has it

 

nice i love that sound!!!!!!!!!!!
man i wish my car dont have air. for sure i get header now!! but i have AIR on my car ugh and scared to removed themm

 

Is that blue smoke I see? No bueno amigo!

 

I ran a new, shorter belt to run w/o A.I.R

 

So did I. But it sounded like he wanted to keep his belt so I didn't bother telling him about running a shorter belt.

 

Idle sounds great. I wonder if you could find a way to eliminate that tin like noise when you get on it?

I didn't go with an AIR delete pulley, been running the pump for 2 months now with no problems. Fasteddi has had his AIR off for years and years without a delete, with no seizing up of the pump. If it does seize up, I'm just going with a shorter belt. Hopefully I have luck like Fasteddi though, and it lasts. What would cause it to seize up, anyway?

 

I have the same question? Does anyone have the answer? Please help the new guy out!

Thanks

 

Hi Guys, not sure if im posting in the right place (new - old person). I've recently purchased a 1991 RS 305 Carby Camaro. Bit of a project for me and my two pre teen sons.

I want to go old school on it with Headers and a big chrome aircleaner. When i looked at the stock exhaust it had tubes running out of them and reading here it sounds like this AIR system. (We had nothing like this in the 70's and 80's when i was working on cars). What is the process for removing it.

Also what do i have to do to remove the stock air cleaner setup and replace it with the big chrome aircleaner?

Thanks in advance for any help here.

By the way i live in New Zealand and the emission laws are exempt for all "Classic" American Muscle cars, so i can pretty much just go with straight pipes if i want.

Cheers

 

i to would also like to know what would cause the air pump to seize up? how does the pump know you don't have the tubes hooked up? makes no sense to me.

 

Because obd1 systems are like cavemen, the pump is just that, a pump its driven y the belt and its sole purpose is to push out air, there's no post catalytic converter sensors so as far as the car is concerned everything is normal. I've had my pump off for 3 and a half years now. The only thing that would cause the pump to seize is failure, parts wear and by spinning it as a pulley you're just doing the same thing as if it were still hooked up, the life expectancy of the part remains the same

 

thanks. I assume your running the delete pulley or did you just run a shorter belt without pully. I still can't decide if i want to go with the delete pulley way.

 

Btw. I did go with a delete pully just for a cleaner looking engine bay. But i to trim down 1/4 an inch to fit it on the air pump bracket. Just thought i would share that if anyone else needed help.

 

does anyone know about mine its got a 4 barrel carb not tpi and i took mine off to get to my plugs will it hurt mine if i leave them off and just block off the holes?

 

ok question.. may be a tad off topic but it sounds like someone here will know- any idea what size bolt is holding the air crossover tubes on the engine on each side? on the passenger side it looks as if it holds the tube from the cat on too... thanks

 

I think it is really funny that people think that the A.I.R. system helps with emissions. It is a farce.

 

It does help. With the cats on, the exhaust doesn't smell so rich.

 

I removed the main components of the A.I.R. system today to prep for header install. From what I can tell, all it does is push air back into the manifolds/headers to dillute the exhaust to "appear" cleaner on a sniffer test. The same amount of Hydrocarbons are still emitted from the exhaust, but at a "leaner" level due to fresh air mixed with it.

I could be dead wrong however . . .

 

basically lol.

 

I don't think you understand the volume of exhaust in CFM vs that little pump. To be able to dilute the mixture that much, that your PPM is greatly decreased would require a small blower!

It helps COMBUST the left over elements in the cat.

Your gonna wish you would have kept all that stuff on there. Your eyes will start to burn and your clothes will stink

 

Oh by the way, we did a test on the Dyno with and without the smog stuff connected and there were no power loss. Just a myth!

 

Do you make 600 hp ?

-- Joe

 

I wish

 

well I figure, with the turbo, 412" engine, reverse manual valve body on a 3 speed automatic, and 600+ hp with 700+ potential, emissions stuff isn't really part of the design.

Well, like I said, I could be dead wrong, and looks like I am hehe. Thanks for the info.


I've driven it for a couple days with the A.I.R. system removed, and I don't notice anything adverse or negative, which to me is a good thing. *I* see it as an unnecessary system in my personal vehicle, so I decided to simply remove it. I would like to think that if it was so important and critical to engine performance, all aftermarket headers would be required to have the A.I.R. ports on them.

Now I don't know much of anything about catalytic converters, but are the ones made today a newer/different design than the factory ones on our cars? Would a newer design cat be more efficient in doing its job, therefore possibly eliminating the need for the A.I.R. system?

Second part to that question, is a faint smell here and there of rotten eggs (basically smelling CO, right?) a sign that the cat is in need of being replaced? I've noticed a few times even before I took out the AIR system.

 

CO has no odor. If you're smelling rotten eggs, that is due to sulfur which is one if the things the cat and air system were designed to reduce.

 

Gotcha. So is that a sign of a failing cat? Like I said I've noticed that sulfer smell for a couple months now, long before I removed the AIR system.

 

I have been wanting to do this for awhile now and finally broke down and did it. I love the engine bay a lot better now. I did find some plugs that I will be using on the remaining air tubes still sticking out.

 

This is just the info I was looking for. I just picked up a 86 z28 and it seems the previous owner did a half *** job of trying to remove it all.

 

The main question is this:

Do you need to be smog tested where you are?

if not? Then yes, the car will run just fine without the AIR system hooked up.

 

Car only requires its annual safety inspection here in Texas due to the age of the car.

 

Just make sure that the inspection doesnt also require a visual check of emissions equipment.

 

When removing the AIR system, do I remove the charcoal canister and these crap vacuum lines as well?

 

I can sometimes smell the rotten egg odor on my 91 RS 3.1L V6 and I still have everything stock. Not very often but it seems to happen more when I get on it pretty hard rather than normal driving.

I am going to try a smaller belt and block the lines coming to and from the pump. There is a thread in the V6 section, specifically this post: https://www.thirdgen.org/forums/v6/6...ml#post5674560

 

No, they are a completely separate system from the AIR pump and cat. You'll want to keep the charcoal canister and it's vac lines. They collect excess fuel vapors from the gas tank and allow the engine to burn them off. I never had an issue, but lots of people here have noticed a strong gas smell after removing the charcoal canister and vacuum lines.

And FWIW, I put them back on the car when I swapped in the V8.

 

because I'm sucking fuel up from my tank through the canister, I blocked off my cannister lines and plugged all the ports. No gas smell here and the car runs fine. This may be my situation though, everyone seems to report a different answer on what happens when you pull the charcoal cannister.

 

I'm pretty sure the fuel vapors come if you vent your tank strait to atmosphere.

 

is there a diagram or step by step instructions to reinstall the smog pump an its componets i need it fora 86 camaro 4bbl carb it needs to pass cali emissions ty in advance i need this asap plz

 

Anyone got any handy tips for removing the torx bolts on the smog pump? Mine are stuck solid and driving me mad... needless to say after several goes one is now starting to round out so i bolted the pulley back on and drove on.... no room to use power tools etc in there either...
