Engine Lubrication: Service and Repair

Lubrication system components, removing and installing

WARNING!
^ Do not re-use any fasteners that are worn or deformed in normal use.
^ Some fasteners are designed to be used only once, and are unreliable and may fail if used a second time. This includes, but is not limited to, nuts, bolts, washers, circlips and cotter pins. Always follow the recommendations in this information-replace these fasteners with new parts where indicated, and any other time it is deemed necessary by inspection.

CAUTION!
^ If large quantities of metal particles or other deposits (caused, for example, by partial seizure of the crankshaft or connecting rod bearings) are found in the engine oil, the oil passages must be cleaned thoroughly and the oil cooler replaced in order to prevent further damage from re-occurring.
^ Do not overfill with oil past the MAX mark on the oil dipstick. Damage to the Three Way Catalytic Converter (TWC) could result Markings.
