We had a cracked head on a 485 that caused fuel contamination and low oil pressure at idle. We found the crack by pressurizing the fuel system with air.
We also had a neighbor that experienced low oil pressure and the culprit was the crankcase filter had come apart and plugged the oil pump inlet screen.
