Air Suction Valve (ASV)

Use a large vise grip of some sort to remove the air pipe nut. Its larger than 22mm and most people don't have wrenches past that size.

12mm bolts hold the valve to its hanger. Remove them.

Now pull the valve up and away from the "stove pipe."

Swap parts and you are done.

One thing I found out when I did this, the hard/easy....was that one Air Suction valve costs $150 and another costs under $20. Ironically the one with more to it costs less. Heres what to do to be able to use the cheap part in place of the expensive one.

Pic of my broken internal pieces on my ASV.

Bottom half of old valve and top half of new valve. The top half of the new valve isnt used.

Here shows the bottom half of the new part and the top half of the old part. The big chunk at the bottom is the old reed valve that broke on mine.

Completed assembly of the 2 parts used to make one good one. You need to take the whole middle section out of the new valve and drop it inbetween these two sections to make your $20 valve worth $150.

Scan from Factory Parts Book, 1986 and 1987 EA82 cars (Wagon, 3 door, XT) with Carb.

Then hook up all the pieces and put a new hose/silencer on and you are done.
