Pics of the setup and how you have this thing plumbed. Do not pass go until you post them.

 

Ok ill try to get pics or a vid soon

 

Do a compression test to be safe. It sounds like a bit of blowby. I have a f20b also. I had it tuned but man even with the thick head gasket I still blew 2 rings. Mine had a thick mist coming from the catch can.

 

milky oil = headgasket.... its toast.

unless you've somehow mis-routed lines and are forcing air into the crankcase
