Oil Leak? PCV system?

Hey Guys, i have attached the video of 2009 BMW E60 LCI N52B30 . I have replaced valvetronic gasket, valve cover gasket, oil pan gasket, still discover oil stain after a week driving... have sent to 2 different workshop to rectify this issues.


Please comment or advise whether this is related PCV system or any others issues.


Thanks Mate

I am having same oil leak problem with my e38 740iL. I am also considering the PCV system and changing the diaphragm. But, I dont have any other symptoms of a bad PCV diaphragm. Thoughts?
