84 Air Suction Valve blowout

[geoff drake]

My '84 GL Wagon (2WD) has blown out the driver's side ASV,become difficult to start, and sooted up that side of the engine compartment. Anybody have one for sale or know a work-around?

Thanks, Geoff in Georgia

If you dont have to pass an emissions inspection dump the system. Search the forum for "the quarter trick" you will see what others are doing. It involves cutting the piping and using a quarter to plug the hole in the exhaust spacers.

Heres one thread of many out there (with pics!)

If your lucky enough your car may be equipped with an AAV as well. In that case, the egr valve will need to be replaced too with one from an EA82 car or at least one without the giant hose barb on it. If your blow out is the spacer itself your luck continues... You must keep the exhaust spacer/s, make a new spacer or change exhausts to ea82 etc.

Tip: P.B. (Penetrating Blaster) its your friend. I like to marinade such things for at least an hour, if not over night. Soak it, wait a bit then reapply. A quarter isnt a smooth flush plate but it works. Knock outs from an EMT box dont work that well, the 1/2 is too small, the 3/4 is too big and requires grinding. No matter, you get the idea. Good luck, no doubt you will tackle this.
