i have a 95' olds cutlass conv that i take execelent care of, its just a sunday driver on nice days kinda car, i just turned 45k miles on it, and do regular maintanince on it, it has a 3.4 dohc engine and i hear that it is what is considered a zero clearance engine, so if the timming belt breaks pistons hit valves "ugly" and "expensive" so with 45k on the clock im thinking of having it changed but even my olds dealer cant give me the straight scoop if this is a zero clearance engine! , i dont mind to spend the money to have it done i just wish someone can give me a straight anwser, i guess its not a real common engine but they were mostly in olds cutlass's and lumina z-34's if anybody has any insight? comments? ideas? im just trying to make a informed desision, the dealer quoted me 450 to 500 bucks for this job. what do you all think?
