The end cover guides the engine oil from the main oil gallery (arrow) to the two oil galleries for the oil supply of the cylinder head and is sealed with a gasket.

The bottom edge of the end cover is sensitive to distortion (oil leak). For this reason, use insertion tool 117 589 00 43 00 to replace radial seal only when the end cover is fitted to the crankcase.

In the case of a leak at the rear, support engine, run and determine the leakage point.
