oil pressure question

For a high volume pump, that is low. Usually in a fresh engine with a stock oil system engine it will go close to 80psi cold over 3500rpm. this will drop to 70-75 hot, and somewhere between 20-35psi at idle hot. This is with 10W hot or 20W hot oil (like 10-30 or 20-50). If it's at 30psi off idle, you have a problem. Check the pickup placement in relation to the pan, and for debris. If the oil drains out with glitter, pull the rod caps on a couple rods and check the bearings. What were the oil clearances?
