Thanks for the data - just did this along with the CCV replacement. A word of advice - When doing this gasket fix, spend some time cleaning up the housing, the block openings, and the vanos oil line. My vanos failed very shortly after doing this (POO14 I thinK). Did some research and found several cases that this happened - suspected cause is introduction of crap into the clean side of the oil supply to the vanos. I replaced the VANOS unit and she runs like a champ - better than ever. On the other hand, the 330 ZHP had 135,000 (bought used) with no indication of the vanos being replaced and it was rattling like mad. Also, the new unit got rid of the classic "ZHP" rattle. All and all a very successful DYI and a big savings on labor.
