Okay I'm asking this question for a friend of mine. We put in an aftermarket mechanical oil press. gauge to be sure. The engine drops right to about 0 psi at idle but its not knocking smoking, pinging, etc... it runs fine. The car has new bearings, the crank was polished but not cut. It also has a new oil pump, and new sending unit. Any ideas what might cause it. It does drip at the rear main but I doubt it'd affect the oil press. I'm stumped. Looking for ideas.
