Conversation Between lucifer_sam and eohrnberger

Hi!
Saw your post and was wondering.

"Now for the important part - I carefully installed the brand new, $300, Oil Pressure Anti-drainback Valve. The failure of the stock valve was what had caused the previous head to scrape itself to death. "

Do you have a Porsche part number for the Anti-drainback Valve? I'm facing replacing at least one, and perhaps both my S2's cams, and I'd want to make sure that I didn't miss something.

Thanks,
Erik.
