I installed another cam this morning, but for some reason, even when i turn the engine over by hand, the belt slips by about 7 teeth, each time I turn the engine over (by hand) it slips to a new spot...what the hell is going on here??? I installed my old cam months ago with no problems, the only thing I can think of that I did differently was when the belt was off the cam gear...I turned the engine a little by pulling on the belt to line it up with the cam gear, then slipped it on...everytime I turn it over by hand it slips a lil....anyone know what the cause is of this?

 

try the belt tensioner, it should fix it

 

well i tightened the tensioner....but you think it could of gotten messed up when I pulled on the belt? anyway to check if it's working right? the belt has tension, it doens't come loose or anything.

 

check the tensioner underneath...theres alil nub on the block..make sure the hole in the tensioner is on the nubb..

 

make sureyour spring is okay and still springy

 

Ok...if you make a mark on the tooth of the timing belt that's right above the "up" mark on the cam gear, when it comes back around, should it line again???

 

sohc or dohc? cuz i was being stupid when i installed my belt on my dohc and didn't relize I had to go around twice (by hand) before it would line up again.

 

No.

 

whew..well everything is fixed now, no bent valves from moving the belt around so much, compression was 150 across.
