Same issue that many people have mentioned before, low oil pressure. I have a test gauge connected to the place where the oil pressure sensor goes. It reads 60lbs at start up. When the temp reaches 195ish, at idle, the gauge goes down to 4lbs then after a few minutes, it goes down to 0. I pulled the gauge off of the hose on the tester and started the truck. Oil squirts out in a very strong stream. So I know there is oil getting to the motor, just dont know if it is enough. Running 15-40 syn.
I really do not want to have to repace oil pump
