Operation of the lubrication system (Audi 100 C4)

The engine is supplied with oil by means of a circulating lubrication system. The gear pump, driven by the intermediate shaft, is located at the bottom of the engine oil pan. All engines have an oil cooler mounted under the oil filter. It is supplied with coolant through a hose and cools the oil passing through it. The drive gear of the oil pump also drives the ignition distributor (some models of cars), however, instead of the ignition distributor installed on the side of the cylinder block, a plug is installed, which is secured with a metal fastener. The connection is sealed with a circular cross-section ring.
