2005 BMW 325i


I got this beemer and when I pull the oil filler cap off it has a bunch of vacuum. Everything I looked at says its the ccv which is a really screwed up German version of a simple pcv. The problem is everything I see about replacing or deleting the valve doesn't have the same system as this one. I took a picture of the motor, you can see the oil cap is in a different place than others and the ccv hose if you look comes out and 90's into the intake. everything else goes under the intake to the ccv. Any ideas

That looks to be a plastic cover. You can probably remove it to have a better look.

Yes the engine cover is plastic. I'll take a picture of it this weekend without the cover. The intake is plastic also.

A little update on this. The car has a M56 motor, not sure exactly what that means other than it has a aluminum valve cover with a pcv diaphragm. Its under a black cap that has to be pried off. Inside that valve cover is a chamber that has tubes that suck crankcase pressure up to the diaphragm and then out  to the intake. The diaphragm helps filter the oil before the intake. If you don't change the oil often enough it gets sludged  up and no more crankcase ventilation. This car had molasses for oil when I got it, and judging from the way it looked that had probably been its life.
