Mein Auto: 2006 X3, 2002 330i
I am going to check out everything that was mentioned. I'll give any intake rubber a more complete inspection, and check the vacuum and goop on the oil cap.

I had the CCV replaced on my 2002 330i after a DISASTER...took the car on a trip last winter where it sat for two days with a low of -20F...when it came time to start I guess the valve was gooped shut and sucked oil into the engine, white smoke everywhere, and a lengthy tow back home. Lesson for all...if you see white goop under the oil cap, replace the CCV. It didn't help that my thermostat was malfuctioning so the car never fully heated up on the way there.
Past ownership: 1987 325is, 1988 325i, 1995 325is, 1996 325i Convertible, 1994 325is black coupe (which I miss).

Current ownership: 2002 330i Sedan with some cool DINAN upgrades, 2006 X3 3.0i
