another dumb question, were is it located? any pics?

Here is a pic of the p.e.v.r. still not sure if its working but the plug runs 2 vacume lines off it, it is located just below your choke on the intake.
In the pic the pevr is unpluged for the shot on my 80'

Can our cars run without the pevr? What are the consequences to running with out one?

Your 83 doesn't use a PEVR valve. Only the 80 and earlier ones have them. If the car has been made to work like the earlier ones you will need it to keep lean spikes from causing detonation.

Really wow all this time looking at my vacuum diagram picture in my engine bay wondering were this was, and it turns out i dont have it, what a relief...loll

 

[mikemcvaney]

can you find one for me or buy another and sell it to me. I have tried and I cant find one anywhere. Your help is deeply appreciated .

Matt put a holley on it they work much better. Mike

what we really need is for you to get the parts and make a mechanical one. i am almost tempted to get the parts for you charlie.:tongue:

I agree charlie sent you the part months ago lets geter done and yes Im a redneck from Nebraska. Mike

A highly technical electrical device that makes the B4B cars fast, like a flux-capacitor.

I wish!The flux -capacitor is called a holley they sell them new at the parts store. Im not going to stop till someone besides me and A.J. tries it the fastest carb turbo was not a quadrajet. Ask fred himself I have a 780 on mine works grreat my stock was modded and would not hald a candle to the 780 or the 650 double pumper . Mike

Its an annoying valve that controls the power valve. Have to control the power valve somehow, vacuume is differant post turbo than pre turbo, and you cant put it directly to the intake because it would blow the metering rods out.

If I find one. I was going to buy the top end off that 79 sport coupe eventually, and I hope it has a good PEVR.

Ive got a vacuume switch and a electric switch that switches on at like 3 inches of vacuume so I got the stuff to make an electric PEVR but I havnt got around to it yet.

Was just going to hook up a line going to the intake from the power valve port and put the vacuume swith inbetween. When the sensor picks up 3 inches it shuts the valve. It doesnt matter if it runs full ritch at 3 inches and up IMO.

Only thing thats stopped me is when I rebuilt my carb I adjusted the power valve and never completly adjusted it right. I hooked the power valve up to the plenum when I put it back on. It idled but wouldnt pick up speed at all. Ran out of fuel. If I eased onto it it would sputter and die. If id smash it it would run good for half a second, then die. Disconnected the line and it ran fine. Mine runs without a PEVR all the time. Havnt had any issues. Should pick up some MPG though.

My power valve opens at 3.5 inches of vaccumworks good. Mike

Just teasing you still have not fini8shed buffing mycar after a year

Ill find the stuff. I know where the switch is but I dont know where the trigger is. Ill get you the part numbers.

what you found a way around the pevr? this is very interesting! will it work on my 80 tta... please share?

This site is all about the early turbo V6 but has info that may help you make an electronic PECV so you don't have to hunt down a stock one.

yes i believe the pevr is the same part exactly! by looking at them. i have been playing phone tag with pontiac to find out if they would make another run of them but to no avail.. seems like no one knows there has knowledge of what i am talking about! drives me crazy! does anyone have the part# for the buick pevr i know the pontiac has a part number # 10010090 and on the bottom of the pevr is 04794. has anyone actually built one of these from the info on that link? have part numbers? i know over on the 301 site i guy dissassembled a pevr and rebuilt it! dont know if it will last but at least he took 1 apart and knows how they are made.

 

[charlief1]

They're a mechanical part so it would have to be re-designed and I doubt any major manufacturer would be interested in making an obsolete part for such a small minority of cars.
