Can someone clarify if it is a timing chain or timing belt. I'm starting to get a little annoyed.

Do they sell a metal aftermarket tensioner for more strength? Also I've never heard of needing a tensioner for a timing chain. I guess all engines are different. It is also very rare in other engines for the timing chain to ever be replaced. I can definetely see changing a timing belt every 60,000 miles.

in basic terms when gm made the 2.2 they fucked it up. nothing new with gm 4 cylinders i might add, so they say to repalce it becasue the plastic tensior goes out quicker than the chain. the chain is good for a long time just the plastic shit goes out quick. and i don't think they make metal ones to my knowledge

I have seen what happens when the timing chain is not replaced in time on those 2.2L engines.If the timing chain is not replaced in time when it fails,bends the valves.That is the only engine damage (1997 and down).The 1998 and up 2.2L engines do not bend the valves when the timing chain goes,figure that out.

Interesting.....good thing I got it changed when I did. Regarding the strange rattling noise I heard post-replacement, by day three the noise was essentially non-existant. I took it in anyway, and the mechanic thought it might be the belt tensioner, that it may have slightly shifted during the work and is causing the racket. I will keep a close eye (and ear) on it. In the meantime the car is running fine.
