Checking the tightness of the oil system (Mercedes-Benz E-Class W210)

During operation, small oil stains may appear on the engine surface. Motor oil penetrates through the pores of the gaskets with large temperature fluctuations, but the appearance of oil puddles requires special attention. This indicates serious problems that must be eliminated immediately.

Possible leak locations:

1. Crankshaft oil seals: front and rear.

2. Timing mechanism cover.

3. Control chain tensioner fixing bolt.

4. Cylinder head cover.

5. Cylinder head gasket.

6. Oil filter housing.

7. Crankcase gasket.
