I'm noticing oil around the (renewed) oilfiller cap, and I suspect that the crank case ventilation system is not right.
Where can I find the PCV valve/filter on the engine to check out?

Cheers

Most newer MB engines use an vacuum orfice instead of an actual valve. The orfice is part of the intake manifold & has a rubber hose that hooks to the air filter.

Thanks MBDOC,
Real sophisticated solution...
Where can I find this orifice on the rocker cover?
Have to remove the airfilter housing I guess to reach the other end of the hose?

Cheers!

Found and checked the PCV hose which turned out okay.
Purchased a new filler cap, an original MB one this time. Valve cover stays clean, so far

Cheers!
