Hello ,i have a 2005 clk200 kompressor (w209) .
im getting warning on my dash saying "Add 1 litre of oil at next refuel"

After 3-4 months its displaying the same thing.So i topped up again.
Now month after that its displaying the same message,But i can smell burning thru the vents,and smoke coming out of the hood.

so with the engine running i can see oil all over the rocker cover and around the filler cap.

Is this a pcv valve problem? if it has one.

Since having the car for the last 4 years it has been ok ,but now i have this issue with the oil.Also since having the car ,On start up theres a slight rattle/Shake on the engine,but after that it just runs fine.Still runs fine and smooth.

What could be the issue with the oil spurting out of the cap when its closed.?

Many thanks
