Oil Pump: Description and Operation

Oil Pump Overview


The oil level must not go above the MAX mark - danger of causing damage to the catalytic converter! For the marks on the oil dipstick. Refer to => [ Engine Oil Level, Checking ] Component Tests and General Diagnostics.

• If large quantities of metal particles or other deposits (caused, for example, by a partial seizure of the crankshaft or connecting rod damage) 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 occurring.

• The engine must not be set down on the oil pan, because the seal between the lower and upper oil pan is otherwise damaged. To set down the engine, use the frame support (T10191).

• Secure the engine to the engine and transmission holder (VAS 6095) when working on it.
