Engine Lubrication: Service and Repair
Lubrication System, ComponentsCAUTION!
^ If large amounts of metal shavings or small metal particles are found in the engine oil, caused by wear of crankshaft and connecting rod bearings, thoroughly clean the oil passages to remove contaminants and help prevent later damage.
^ The oil cooler cannot be sufficiently cleaned, and must be replaced.
^ The oil level must NOT exceed the MAX mark on the dipstick. If this level is exceeded (too much oil) the catalytic converter may be damaged.
