I have a 2001 Grand Prix Se 3.1L. I am burning through serpentine belts rapidly. I have two old ones that are torn in half but not completely broken and a new one just in case them two fail 
. but i seen a post today about the harmonic balancer going bad with rubber gasket in there. wondering if that is the problem i'm having. When i put the new serpentine belt on and ran the car, i could see after i ran it and shut it off, that either a/c compressor pulley or Harmonic balancer pulley is out of line. Is this a common problem with this car?
Recent work i've done on this car was:
-Removed heads got rocker arm holes tapped from machines shop ( i think they put inserts in not 100% sure)
in that process i moved alternator and ac compressor to remove the heads. done that twice.
-Also replaced the tensioner pulley assembly with in the past 2 year
Is there possibility that my installation of alternator and ac compressor bolts(motor mount) was wrong. Or is it the Crank shaft rubber thing i read about.
Need help asap just finished tapping 2 rocker arms bolts with heads in car, after it has been sitting for a year and a half, i was to the point to rip the heads out and replace with re-manufactured ones, because i was worried about tapping the heads while in the car or the other rocker arms to continue to pull out.
Any info or links would be greatly appreciated
