Okay.. I'm really puzzled about this. As some of you might remember.. my timing chain slipped during the summer and busted my motor. I put an m44 in with all new timing related parts (chain, guides, tensioner etc.).

Somehow I still have a lot of chain noise as if there is some kind of interference/wear going on. I took the valve cover off and took a peek.. everything appears to be okay. The noise becomes very noticable around 3500 rpms. Anybody have any thoughts?

Thanks

Rachel

have you changed the tensioner?

Also, was everything torqued properly?

Yep, sure was.

Any other ideas?

I don't know. But this makes me think, I've had predictable noise around this rpm, esp. partial throttle and decel, but figured it was somethign else. I still hope its this shady heat shielding rattling around in the rear above the my muffler.

Well... When i started losing oil pan bolts, i would get intermittent chain noise... Maybe check yer lower pan for bolts with an oil change?

Check the lower timing chain sprocket, I will bet it is worn and the chain is stretched. Mine was doing this with a new tensioner for a while before the chain started to break up.
