timing chain & gears

[linnharding]

I only hear the sound at idle, and that's when it's below 700 rpms. Can't remember if that's hot or cold. Nice to know our engines
I'll wait on this one-too many other jobs to do before summer. Thanks for the information.

Rebuilt my 87 van about 30K ago and used a timing chain from Rock Auto. It was a close-out item and very cheap. On inspection, it looked good. Made in Japan and appeared identical to my old one, which I assume was the original. Neither chain said "Toyota" on it but both had the same identifying letters stamped into the side plates. So far, no problems with the timing chain, pistons or bearings.
