Can someone help me confirm what I think is timing chain rattle? I can only hear it just above 2500rpm and only with the radio off. It is a faint rattle. It is not the dieseling sound everyone is referring to. Is there a possibility that it could be my the tensioner pulley bearing for the serpentine belt on the front of the engine? It makes that same sound when I spin it.
The truck has 130,000 miles. I have the LH valve cover off and the timing chain tensioner looks really good. Tonight I was even turning the harmonic balancer back and forth looking for slack in the hidden jackshaft chain, but there was almost none. I would have thought that if the jackshaft adjuster had exploded as in some of the pictures, I would have alot more play.
I thought I had a major problem with this slight noise, but now I'm not so sure. Can someone help me? How loud should this noise be?
Thanks guys
