I have determined today, with a dial indicator, that the cam gear is cocked on
the on the cam shaft. I mounted the dial indicator where it would measure the
run out of the face of the cam gear. This was done by placing the indicator tip
on the forward lip just under the teeth on the gear. From t

Good luck! I'm hanging on each report like a Jame
Something had to be out of round, though there would be some indication of
that through bad harmonics I would think. Is it possible the bearings had
moved or slipped? It could have been further into the engine allowing the
