Mein Auto: e46 330xi
Thank you for this thread, very nice info.

I went ahead and did this same thing to my e46 330xi and I have too much vacuum being created in the valve cover area, I can hardly remove the oil fill cap and I have valve cover gasket leaks developing.

I installed the PCV valve so that the intake can pull as much air as it wants, I was under the impression that this was the correct way to install it.

I believe that you are using this valve to actually limit the amount of air the intake can pull through the valve cover. If so, I have the valve backwards.

Can someone confirm?
