I know this will come as a shock but people have been posting the info you are seeking for YEARS on this forum. You are not the first to discuss this system which in BMW language is called an "oil separator".
Try a little reading effort in a few How Tos articles and then post.

Not trying overly to smack you too hard but you are making way too easy.

Tip: all that mayo in your breather tube is causing your system not to function as designed.
TIP: Get yourself a TOYOTA Tundra or Sequoia for the winter and you won't have to deal with that Mayo in the engine.

I have it all back together and still fighting a lean condition on both banks. I replaced the vacuum hoses on the back side of the intake and at the valve on the front of the exhaust manifold. I also replaced the hose going to the firewall.
Check the hose that connects the airbox to the throttle body and Idle Air Control (IAC). It is usually the small rubber hose that is connected to the IAC that is cracked and allows unmetered air into the system.
