3-13. FUEL INJECTOR LINE RUPTURE
General Information
Failure of an injector can be noticed by a loss of power or increased fuel consumption.
If either occurs the injectors and fuel lines should be inspected to determine the cause.
If the crankcase oil is overfull or has a diesel odor, remove the valve covers and inspect
the fuel lines for cracks. Operatre the engine with the valve covers removed to check
for fuel leaks. Unrepaired injector lines will cause the fuel to enter the crankcase,
diluting the engine oil and resulting in early engine failure .
