    I'm working on a 05 379 PB and after driving it for 5 minutes the oil light turns on and the buzzer sounds. I don't know know if the light /buzzer is low oil pressure, high oil temp or what. I've changed the oil pressure sensor, changed the light panel, cleaned all grounds, changed the low air sensor (since the share the same speaker). Anyonecrun into this issue?

    I’d be slapping a mechanical oil pressure gauge on that pretty quick. No matter what engine it is you should find a plug in an oil galley somewhere on the block. Hook up a mechanical gauge and check it. Maybe its trying to tell you it has no oil pressure.
