What’s Wrong

The tightening force of the injector mounting nuts may be insufficient. This could cause combustion gas to leak from the injector and contaminate the engine oil within the cylinder head. This in turn could cause the engine oil strainer to become blocked. This could cause the engine to stall. Engine Pressure Oil Light appears along with the engine malfunction indicator. Possible Engine Stall without Warning.
