I am trying to figure out what part I need to replace. I have a 2010 535i GT, (F7 ). I am getting a high pitch noise after the engine has been running for a while I get a high pitch noise. It going away during acceleration and comes back at idle. It also goes away when removing the oil cap. There is a suction on the oil cap with the engine running. In during some some research I know I have a crankcase issue. I have replaced the PVC valve on top of the valve cover with no success. I have also relplaced the crankcase vent hose with no success. Does anyone know if there is a crankcase vent valve that I need to replace. I searched pelican parts and auto haus with no success.
Please help
It does sound like a CCV issue

In my experience, you need to replace the complete valve cover. It's fixed every one I've every had with that noise.
