I have a 1997 Larson that on a cold start has good oil pressure but after about 15 minutes of running at about 3000 rpm oil pressure starts to drop(about 20 PSI at 3000 rpm not good need 10 PSI for each 1000 rpm) Pull throttle back to idle and 0 oil pressure.
Engine burns no oil
Engine has plenty of fresh oil
Engine has no bearing noise
Engine does have some lifter noise at 0 oil pressure
WHAT NEXT
