Most all who've done this wondered the same thing and for the same reason: "if left intact, then someday I could re-install it and make it stock again."Has anyone pulled the air pipe without cutting it? If so any words of wisdom would be appreciated.
Afingmen....yeah it needs to be left on the vehicle in California to pass visual. You may get lucky at a smog test that does not know or care but for the most part our 20+ year old cars get "Test Only" smog notices and those shops are under scrutiny (read sting cars are brought in by CARB) so they play by the book.The one notable exception to this being CA vehicles which have to pass a draconian spate of emissions testing and inspection. They must be kept intact. And for CA owners who believe the TSB label allows you to remove the system, no. It doesn't. It merely allows you to disable it.
But if you live, well, anywhere else in the whole World besides CA, then ditch it.
Visual inspection "could" be a problem is removed. This has been discussed numerous times here.Will deleting the air pump affect passing emissions?
You don't mention the model year of your car. TSB applies only to 95-96 model years, as mentioned at least once in the previous 200+ posts in this thread.Will deleting the air pump affect passing emissions?
these have a electrical motor pump NO pulley.. now back in the old days 1980's the air pump was belt driven.I know this is an old thread and I did not read every post but what do you do about the missing pulley when you take the pump off do you need another belt or a pulley delete
gut the air pump.Phantom, If you have a TBI car you can use this Chevy 10129569: Smog Pump Eliminator Includes Bracket and Pulley | JEGS
Or take out the pump and use a different length belt. There have been posts on doing this in the past. Although I haven't put my engine together yet I bought the pulley and bracket. You keep the stock length belt and run the belt the same. Also it has a cleaner appearance. IMHO Another option I have researched is to gut the pump and run it.
The 91-93 fan belt can be rerouted to allow for the loss of the pulley. You need a different length belt as well. I would have to check the belt, and the routing. Another possibility is to get an idler pulley that bolts into the space for the air pump.I know this is an old thread and I did not read every post but what do you do about the missing pulley when you take the pump off do you need another belt or a pulley delete
possible for a quick fix use marine tex on the hole. give it 24 hrs to harden .. use a heat gun to increase cure time. I did this years ago worked for many years held up good.Thanks for all the input it's a 95 Cadillac just bought it last night and saw the tubes going in the manifolds and I believe one of them is leaking
