Engine Knock Vs. Timing Belt Tensioner

[Ebenezr]

I can't get to it. Prying the cover back I can't do. When I put a stethascope on it the tap is loudest coming from the timing cover top bolt which enters right into the no. 1 area in the head. It will have to be torn apart to check but for the engine runs great. I am going to rev the engine today like BigSwede said and see if it disappears.

My engine tapping goes away above 2500 rpms too and the engine runs great.
I need to open the timing covers and take a look see too.
