Oil pressure reads perfect when at idle and goes up as you raise the throttle, no fluctuations at all, I've tried pulling plugs to see if it was a specific cylinder but no change with each plug I pull.

The flywheel has no play in it and neither does the balancer on the front.

I guess I will have to pull the valve covers and check things out underneath em

These little things without numbers, do not tell us anything. If all was perfect, your engine would not sound like it does. Remember, we can't see any of the facts way over here.

Ok I got some numbers on the oil pressure

Cold engine 40 PSI in Park/ 35 in drive

Hot engine 15 PSI in Park/ 10 in drive

its about 27 PSI at 1500 RPMS and about 37 PSI at 2000 RPM's
