Hello I have a 1998 grand prix 3.8 superchargedo stick motor I put in myself out of a 98 Buick I'm having a bad oil leak behind my harmonic balancer it's leaking all over my under carriage and passenger wheel. I need to take off the balancer to replace the front crank seal but I'm having a hell of a time getting it off. I heli coiled the holes in the balancer but it keeps breaking bolts I've heated it with a map gas tourch and it still will not come off. If anyone has any advice I'll take it.
