I cleaned and brushed all the grounding straps before engine install, so I'm guessing that is not it. I think Jake hit it when he suggested it is the SUM of wear on all the parts...5 chains...all cam teeth....CHAIN RAMPS....tensioners...etc. I believe I am going to have to tear down and remove cam covers and time the hard way. I do not think there is another way. If it is the sum of the parts the big question is which parts need to be replaced?? I am thinking about starting with chain ramps and maybe chains.
