Well, me too. That's something my mechanic told me. He's like a philosopher mechanic. It might have something to do with chains stretching and the drive parts wearing. OTOH, the chain won't break. My guess is that people with a lot of miles on their engines will just live with retarded valve timing and chain noise - because they can.
