Possible Causes
- Loss of lube oil pressure.
- Oil level low; oil leak, oil consumption or incorrect servicing.
- Oil level high; incorrect servicing, fuel dilution from tandem fuel pump or fuel dilution from injector "O" rings.
- Oil contamination with coolant; oil cooler, head gasket or porosity.
- Low reservoir level; engine built dry (not pressure lubed), prolonged period of not running or excessive cranking without starting.
