Doug&Deb Posted May 25 Report Share Posted May 25 Okay this is a weird problem. My oil pressure fluctuates between 10 and 40 lbs until I get a few miles on the road then it settles at around 40 and stays there. This is a rebuilt engine. It didn’t do this on the test stand. I’m going to hook up an aftermarket gauge to see if I get the same results. What else should I check? The engine doesn’t make any noise when the pressure drops and there’s no power loss so I’m stumped. Quote Link to comment Share on other sites More sharing options...
