Well dang I finally got the timing cover off, at first I was upset everything looked fine the chains were tight other then someone put cheap Chinese parts on it, it looked ok. Then I felt the tension on the driver side chain down around the crank sprocket the chain flops around +/- .250 looks like the chain was dragging on the crescent shaped land on the oil pump the damage does not look bad it just scratched off a small bit of the land. what a pain to get that cover off, now I have to get
the cam covers off to change out the chains/sprockets. I don't know if the chains stretched or just the tensioner went bad but something is not right...
it happened suddenly so I think the tensioner failed if the chain stretched it would have happened slowly not all at once. it has cheap plastic tensioners and the chains look like they are very low quality
