I just received a proper smoke machine from Amazon to test for leaks properly. Hoping to use it within a week. I'm getting married in July, so things are very busy right now! Tough to find time to work on the car. I can definitely say that the BMW solenoids made 0 difference. I wish I could return them! I'll keep you guys updated as I go along.
There is one other thing I checked yesterday. I saw a video where a guy was getting Vanos codes and his car was missing the oil filter cage/oil return plug thing. He put the cage in and his troubles disappears. My filter cage was in place, so nothing to be gained there.
