W211 Engine Oil Leak ?

[WML888]

Need help here.

Is this normally caused by faulty Supercharger ?

If not, what need to be fixed ?

 

Thanks in advance.

I don't own a Benz, but from the photo, that area you highlighted appears to be where the camshafts are. They should be attached to the sprockets where the timing chain/belt drives the cams. Could be a leak on the cover that encloses the timing chain/belt. Or could simply be a rocker cover gasket that's leaking. Your supercharger should be the unit attached on the right of the picture, where your air intake piping leads to.

i had a slow oil leak at the camshaft area. turned out to be the oil seals. just changed the seals yesterday. now monitoring if there's still leakage.

 

btw my leakage is very slow one. 5000km lose abt 500ml (check from dipstick).

That section highlighted has got nothing to do with the external supercharger module (where the CAI hose is directly connected to).

That section is where the DOHCs are located.

Valve/seal leakage likely.

Get workshop to open up the cylinder head to check.

Update (May 12) :

Changed the oil seal of cam sensor, and monitoring now... Should be ok.

Thanks all !

Hi,

 

How much it cost to change the oil seal ? Mine is slightly oily.

That's the infamous camshaft position sensors leak of the older M271 engine.

 

the oil will mitigates along the wires, to the main harness and sometimes ECU and O2 sensors, throwing all kinds of error codes.
