ok so i got the new cam gear on and the timing is right and all that shit but my tensioner is fucking up. i was told to turn the crank a full turn, so i did, then i was told to tighten the tensioner, so i tried. if i try to tighten the tensioner half way through the revolution is tightens as normal, but when tighten it after a full revolution it will get kinda tight then loosen. i was wondering if im doing something wrong or what. i dont know if it matters but sometimes the timing belt is loose on one side of the cam gear,tight on the other, then later its vice versa. what should i do?
