Symptom | Possible Sources | Action |
Loss of oil | * Oil leaks on components that are either coated in oil themselves or on components local to them. | * CHECK for evidence of oil leaks on components. Use an ultraviolet (UV) leak tester if an oil leak is not evident. INSTALL new gaskets or components as required. |
* Internal or external leak at the oil cooler. | * CHECK the coolant expansion tank for a film of oil on the coolant surface. INSTALL a new oil cooler or oil cooler gasket. |
* Leak at the crankshaft seal. | * INSTALL a new crankshaft seal. |
* Leaks from oil carrying components or basic engine. | * CHECK for cracks in oil-carrying components of the basic engine by means of a UV leak test. INSTALL new components or seals as necessary. |
Oil consumption | * Use of the wrong type of engine oil. | * DETERMINE the last type of engine oil used and compare with the specification. Change the engine oil to the specification. |
* Faulty positive crankcase ventilation (PCV) system. - Hoses or ventilation or breather valves are blocked. This causes excessive pressure in the crankcase which causes more oil to enter the combustion chamber. - PCV oil separator is faulty and engine oil can enter the combustion chamber through the intake manifold. | * CHECK if the PCV system is operating correctly and repair as necessary.
