NOTE: The end cover guides the engine oil from the main oil gallery (arrow) to the two oil passages for the oil supply of the cylinder heads and is sealed with a sealing compound.

For this reason, the radial seal should be replaced if possible without removing the end cover.

If a leak exists at the rear, first of all clean engine and spray dried surrounding area with Mercedes-Benz white contrast spray, Part No. 000 989 03 59. Support engine, run and determine leakage point .

The running surface for the rear radial seal on the crankshaft is hardened and ground without a spiral.
