2002 isuzu axiom 3.5 (timing belt issue)
 

hi all, ive got a problem. i have an 02 axiom and the pulley bolt bent a bit and the timing belt now rides crooked and broke.i have retapped and heli coiled the thing a bunch of times with a new bolt in but its still riding crooked and rubbing on the head. is it supposed to be at an angle or something? any ideas would be appreciated much. thanks all
