whats the question?
- 2004 Cavalier - 124k, owned since new
well, i know that timing belts have a reccomended change interval, usually 60,000 miles. i would like to know if they recomend a change of the timing chains on thier engines. well at least the 2.4 TC and the ecotec, as i have one of each. i havnet found anything in my owners manual, but considering the early ecotecs had chain issues, i was wondering if they had any recomendations, especially since my 2.4 is at almost 130k, and my eco is getting close to 100k.

as far as i remember, reading about anything "official" was that timing chains should not be changed. then also, that they should be pretty good for about 150k miles.
then again, its the jbo.

We never changed timing chains, only belts.

The chain in my 130Kmi old 2.3 looks like it's brand new still when I had it out last. Chains usually last longer than the engine.
