How do I know if I have air injection reactor or non a.i.r.? I have a non stock motor. 70 sbc block, 88 tbi swapped in from k5. I have a smog pump. Is that what that is? thanks. dont know much bout this stuff and im shoppin for headers.
 
If the pump is original to the truck than yes.All it does is pump air into the exaust to make the cat run hotter so it burns better for cleaner exaust/lower emitions.If you still have a cat or cats Id leave it at that and remove the air crapp because your standards are high and youl be exempt in a few years.BTW if your emition routing sticker is still presant it will show the air pump in the diagram.
 
so i found some shorty headers with the air tubes coming off the top of them, so they could be used with my truck as long as i hook up the air. or i could plug the holes and leave it alone. my choice right?

Just get regular headers and ditch the AIR setup. Unless your in CA its VERY doubtful anyone will even notice.
 
but if you run cats, why not just run the air pump. Supposed to clean up the exhaust better. You aren't spending any more money to do it either. You aren't giving up any power running the air pump, they spin super easy with no drag on the engine.

and you never know when laws will change....

I would plug the air holes and remove all the emition parts except the cats or cat for now to clean up the engin bay.They installed the pump to pass strict fed imitions limits when new but no longer needed.Im still a little fuzzy on what you have.Is it a 70 or 88?If it a 70 or 84 and older you need nothing at all not even a cat.If its an 88 you still need at least a cat for now.

other than "cleaning up engine bay"
what's a good reason for removing anything?
Seriously
I come from the worst state for emissions standards. I hate it, but understand it. I'm going to fudge my truck by getting rid of the computer, but it's still clean. I still have all emissions equipment, working too. I guess you have to live in smog to understand. Neither cats nor air pump will cost you power.

money.
 
but he has all this equipment already
maybe the headers will cost more with a.i.r. tubes
 
hmm, my '89 Burb has a Cat, no air pump, the '94 pick-up has a cat, no air pump,,,,:confused: all factory BTW.

Theres the intial cost of installing it and the later cost of maintaining it when something goes bad.Its always about money.My 84 has 2 cats and leagaly I dont need them because no more imitions for me.But when 1 goes bad Im taking them both off and selling them to the scrap yard.
 
Yeah, i have an 88 its just a 70 block. I need to run the cat for another 2 years so i bought the headers with air tubes. need to run a cat for two more years. oh well.
 
You are BOTH incorrect. If your vehicle was originally equipped with catalytic converters then they are required to be there as long as the vehicle is registered and driven on the street. It is a FEDERAL law, not state by state, which says factory emissions equipment can NOT be removed or modified. Just because your vehicle does not undergo an emissions inspection, sniffer test, or whatever you want to call it, doesn't mean the parts are not suppose to be there AND in working order.

With that said, on a vehicle not requiring a sniff test the inspection station tech is supposed to open the hood and look under the vehicle for all the required equipment (smog pumps, cats) originally installed on the vehicle. Do they all do this? No. Which means sometimes you can get away with removing stuff.

For those vehicles NOT originally equipped with an A.I.R. pump, they have a cat converter capable of operating properly without it. It lights off faster and runs at a higher temp to burn off the hydrocarbons. Most replacement cats made today are this type of cat making the A.I.R pump useless.

For those vehicles not originally equipped with an EGR system, they run what's called a 3-way cat. It has a catalyst that burns down the gasses that cause Oxides of Nitrogen (NOX) as well as the normal hydrocarbons.

It's your vehicle and you can do what you want but you are the one paying the fine if you remove this stuff and get caught. Personally, I will be removing the AIR stuff and replacing the cat with a better one. But that's me.

Move to CT.I know in mass they still do safety inspections(sucks to be you) still but in CT no safty inspection unless just bought at a dealer.Thats not to say you cant be pulled over for a safety violation and issued a fix it ticket but my cars are all safety compliant so I dont worry about that.Vin verification only if bought out of state.No emitions testing after 25 years is a federal law so who is gona inspect for the presance of factory items if your not required to go to an inspection station and there no longer required?And the reason these items are no longer required is because cars 25 and older are hard to find(hardly any on the raod any more) and the cost of these items usualy is more than the value of the car so its not imposed.Is there an emitions police force Ive never herd of that enforces laws that dont exist?You must be thinking of Cali where you cant remove anything for any year no mater how old.That is the law in that state and all states are differant.Cat and gas cap is the only thing checked for during a required emitions test.Ive been modifying my cars and trucks for the last 23 years since Ive had a licence so I am very familiar with the laws.And dont forget as I stated earlier I lived in mass for more than half my life at this point and was a cirtafied state emitions inspector so I know the laws there very well as well.Hell Mass now has a new law where you cant drive with your ball mount in your hitch because people cant walk through a parking lot without wacking there knee on it.$250 fine what a joke.And please dont hug a tree and say its the right thing to do next.And your coment about cars today not having air pump is wrong.They have pumps operated by an electric motor which does exactly the same thing but is computer controled.GM is that way anyhow.You seem to be missimformed in every way.So no its just you thats wrong.:haha:

who's wrong?? :D :doah: :tongue1:



Electric air pumps?? never seen those, and as stated previously by myself, I have TWO trucks that DO NOT have air pumps installed on them, FROM THE FACTORY. NO A.I.R. tubes on the manifolds, just EGR's and Cats.

anyways, i was just havin alittle fun,,, did i get everything (everybody else :thinking::tongue1:)

aside from paragraphing :D

Here's a good read for you...

I was not eluding to some "emissions police" just stating a fact. If you were to get pulled over, lets say for too much lift, and a trooper really wanted to bust your cajones he could start looking at your vehicles mechanical systems. If they saw no cat/cats you could get a fine for it. Hypothetical and unlikely, yes, but it could happen.

And dont forget as I stated earlier I lived in mass for more than half my life at this point and was a cirtafied state emitions inspector so I know the laws there very well
I was a Mass State Vehicle Inspector also, although I have let it lapse since I stopped working on cars for a living a little more than 10 years ago. The rules haven't changed, they've only gotten more strict.

And please dont hug a tree and say its the right thing to do next
No, I will. The 4x4 sport and our vehicles are under constant scrutiny by people who don't have a clue. Land closures, lift laws, and our rights to modify our own vehicles (trucks, cars, whatever) is a constant fight. Prius driving hippies are trying to make it so all we can do is get in our trucks and turn the key, no more mods, no more tuning, just driving... on pavement.

And your coment about cars today not having air pump is wrong.They have pumps operated by an electric motor which does exactly the same thing but is computer controled.
I didn't say all cars today, I said "those cars not originally equipped". This was to inform the original poster as to what different types of converters are out there and to make whatever decision based on being informed. I didn't feel it was necessary to get into all the different types of AIR pumps out there.

Any more winners you want to throw at me?:waytogo:

Let me know where to send the aluminum foil so you can reinforce your hat.:rolleyes:The government is watching you so close your shades.:haha:
 
Greetings fellow Chevy truck owners!! I am in the process of restoring a 1987 V10 Suburban with a 350 in it. The catalytic converter, air pump, brackets, exhaust manifold tubes/check valves are still there. BUT, the right rear exhaust manifold air injection tube is just pointing down....going nowhere. ANY BODY have a clue where I can find where this goes? I don't remember, even after I worked as an Automotive Technician for 27 years.
 
I'm pretty sure MA doesn't require an emissions test on a vehicle over 15 years old--but since my diesel is of '82 vintage and hasn't had to be "sniffed" I'm not 100% sure what the law is today--I know that was the cutoff year a couple years ago..

Few places to a "visual" inspection under the hood,I don't know if its required here--but I hear now they have cameras under the vehicle to view the undercarriage for rot damage or missing catalitic converters..

I have to get my truck a sticker by the end of this week,it expires this month..hate throwing $35 away on a sticker when it could be put towards fixing something..just a farce the state uses to get more revenue out of us,it makes no one "safer" really..nor does it make the air any cleaner..they just want more money from us..

FEDERAL LAWS override state. If it came from the factory with emissions, by Federal law you cannot remove them legally.
