Hey thanks loren!
I thought it was the chain, but I just popped hte
valve covers and find that the cahin looks really
tight (maybe a 1/4" play?) does hat sound about
right? It doesn't look worn or anything ....
but maybe it loosens up under power????/
If the chain isn't VERY tight, you have a problem. The tensioner should
keep the chain tight even after it twice as worn as the limit for chain
replacement. You need to MEASURE chain stretch. Set the mark on the cam
sprocket to align with the mark on the cam tower (only turning engine in
the direction of proper rotation - by turning the crank - not the cam)
and read degrees of stretch off of the crank damper. More than 5 degrees
of stretch and the chain needs to be replaced. At about 10 degrees of
stretch the pistons and valves begin to collide.
