I'm looking at a '02 wrx 97k, a few mods (find me one that doesn't have any, and I'll buy it) that on test drive is solid, drives well, etc. However, I noticed that when I was deaccelerating with the car in gear (not engine braking) that there is strange sound coming from the engine compartment. Not a grinding in the metalic sense, but only there on the deaccel, not on acceleration. I'm thinking it might be the timing belt/tensioner, not sure. Obviously I'll have the dealer investigate before I buy, but I would like to arm myself with knowledge first if possible.
Second question, piggie back: what possible tests can I do to figure what kind of shape the transmission is in (manual). I know the whole glass thing, I've done me research, search is my friend, etc. Nowhere does it say how to check and see what kind of condition the tranmission is in.
I'd love any input.
