E90 320i engine breather

[Manfred]

Hi

I have an e90 320i 2010 model.

Everybody is talking about changing your CCV valve.
My engine doea not have one.
The pipe from tapper cover goes straight to intet manifold.
My oil consumption suddenly is high also.

How is that possible?

Make sure your vacuum pump isn't leaking. The oil drips onto the cat and burns up. So no oil leak will be evident. If the car is slightly smoking, the valve stem seals might be on their way out.

My car is not smoking.

But i see on my model there is a membrane inside the valve cover to control the crankcase pressure and i think its the culprit.
