I am a firm believer in stickies. If you have good threads (try to keep em to the 04-08 though!) post em here. I am going to try to keep this updated and organized. The search sort of worked I did a little manual digging.
Fortunately things like "cam phasers" was easy to find because even though the search removed the word "cam" the only place "phasers" usually appears is in relation to cam phasers
