Well, I checked my cam timing and it is completely off!

Any tips/sugggestions on how to adjust the cam timing? Better, how do I adjust the cam timing?

Thanks for all the help, My TC may be at Carlisle at this rate!

I had the same problem... but I think that I aligned mine totally ass backwards of how I should have but it worked great... I never could figure out how to get the tensioner loose so I used a 3' extension to loosen the belt after loosening the bolt that holds the tensioner in place

In a nutshell... Remove dist cap. Rotate crank pulley to TDC, and see if rotor is pointed at cyl #1 plug wire terminal. If not, rotate the crank pulley 360 deg back to TDC and see if rotor lines up now. Remove plastic timing belt cover, if you still have it. Loosen the tensioner lock bolt (the bolt that goes thru the arc cutout) and the pivot bolt. Loosen this bolt only a turn or so. Pry the tensioner pulley out of the way with big screwdriver or similar, and tighten lock bolt. Set cam pulley mark lined up with center mark on plastic tab. If the plastic tab is broken off / missing, run a string from the center of the cam pulley bolt to the center of the aux. shaft pulley bolt, and line up the cam pulley mark on the string. Loosen tensioner lock bolt to tension belt, and retighten lock bolt. Recheck cam timing to be sure it didnt change. Retighten pivot bolt.
