Hi everyone. I just purchased 1987 turbo II about a month ago. The car is in amazing condition and only had 101500 km on it when i bought it. anyways, i've put about 4000km on it since i've bought it and im starting to try to learn everything i can about the engine, which leads me to the reason im posting. I can't seem to find the blow-off valve. my buddy told me that it might not have one, but i thought that if it has a turbo, it has to have a wastegate. so i bought the workshop manual for it but the only thing i can find that would apply is the air control valve. basically what i'm asking is have i already found what looking for, is my buddy right, or are we both way off? thx in advance.
sidenote: I'll post some pics as soon as i figure out how.

A BOV is an entirely different animal, It's a valve that blows off boosted intake air to atmosphere when the throttle closes as in when you lift off the gas pedal. A wastegate bypasses exhaust gasses before it reaches the turbine fins.

alright thanks for your help. at least i know the difference between the two now. from what i can understand from that link, the tII engine doesn't come with a blow off valve then?

It does have one, look on the pass side by the turbo it comes out of the aluminum pipe on s4's(86-88) and the plastic piece on s5's(89-91), has 2 large hoses, and 1 smaller one, should have a blue sticker saying something like bypass valve or something.
