'82 16v: Necessary to preemptively change timing belt?
Hello - this is my first post:
I just recently got a 1982 928 with 80,000 miles. It seems to be in great shape. I don't know a lot about cars in general, or these specifically, but I'm starting to learn (slowly).
Anyway, I brought it in for an oil change and the mechanic stressed to me several times that I should replace the timing belt if I don't know when it was last replaced (which I don't). This was just based on his experience with the damage that can be caused if a belt breaks when the engine is running, not because he saw anything indicating a problem.
After doing some reading, it seems like that is particularly true on the later, 32v 928s, but it's not clear to me how necessary it is for a 16v 1982. This document (http://928intl.com/repair/T-belt1.pdf) says:
The factory-recommended replacement interval for the timing belt is 60,000 miles, but more conservative or pessimistic owners often observe shorter intervals, such as 40,000 miles. There is general agreement that age should also be a factor, with replacement suggested at no more than every four years, no matter how much or little you've driven in that time. If you don't know when your belt was last replaced, you should seriously consider replacing it, especially on a 32-valve engine.
