Damo 23 Report post Posted June 17, 2007 Link : CAM GEAR This is a Korman adjustable cam sprocket for all 2002's and 320i's made before 1980. These are handy for restoring cam timing after head or block milling or for degreeing a performance camshaft. The design uses precision slotted mounting bolts and a pin eccentric . Up to 7 degrees of camshaft advance is possible. Quote Share this post Link to post Share on other sites
