Today, I noticed my oil pressure has changed! The engine was starting at 60+ pounds cold then settling down to about 40. Would go to 15-20lbs hot. Now it's starting at about 20lbs and goes down to 5-8lbs hot. No rattles or noises, the pickup and tube were cleaned before installing. I'm hoping that a piece of trash got up in the oil system OR perhaps the bypass valve in the oil filter is stuck open. Any Ideas on this? Chuck in NH
