hey guys got a bit of a problem. first off im in need of help from sombody who has a bit of experience with s50 motors. right now im in the process of rebuilding one but im having some trouble with the splines that link the cam sprocets to the vanos, mainly that when i put the splines into the sprocets the exhaust spline will get stuck too far back and i have to pull it out and start over. and the intake spline just wont ingage all the way. i have been looking at the tis documents, but the problem is that parts of it are conflicting. if anyone has any insight please help!
