been related to age. Almost every coolant hose has needed to be replaced at one time or another. PS leaks have plagued me since I bought the car too. Some of the clutch/tranny issues I have had can be attributed to the mods/abuse. Also had a stock injector go out out on me and the stock diff bushings are shot. Also i've had brake issues due to a sticking caliper and a tensioner pulley disintegrated once (somehow I didn't bend my valves!). Luckily I haven't had to many issues I can attribute to my performance mods yet.
