must be repaired or replaced.
3.
Fuel leaks into the lubrication oil. Fuel leaks will cause
high fuel consumption and low engine oil pressure.
Fuel leaks into the crankcase from the fuel transfer
pump.
Fuel leaks past the valve in a fuel Injector nozzle.
The pressure setting of the fuel injector nozzles is too
high.
The seal at the front of fuel injection pump is defective.
Fuel leaks into the air inlet manifold from the air inlet
heater.
Adjust the component. Replace a damaged component.
Problem 16
Coolant is In the lubrication oil.
Probable Cause
1.
The cylinder head gasket is defective.
Install a new cylinder head gasket.
