General description of the engine (Audi 80 B3)

The engine is a 4 - cylinder, in-line, overhead camshaft, traditionally mounted at the front of the car. The crankshaft has five main bearings, the center main bearing shells include flanges or separate thrust washers to adjust the crankshaft lateral play. The camshaft is driven by a toothed belt from the crankshaft sprocket. The belt also drives the intermediate shaft, which is used to rotate the distributor, oil pump, and fuel pump (on carburetor engines). The valves are driven from the camshaft via hydraulic tappets, and the valve clearances are set automatically.

The engine has a full-flow lubrication system from a gear-type oil pump installed in the sump and driven by an extension of the distributor, which is independently mounted on the intermediate shaft.

The oil filter is a cartridge type, installed on the left side of the cylinder block. There are two oil pressure sensors located on the oil filter housing, the lower one operates at 0.3 bar, the upper one at 1.8 bar.
