I have a few threads about 5 threads in that have destroyed the hub bolt that goes into the crankshaft for the balancer and pulley. anyone have any advice about how to fix these threads? can i run a thread chaser through it? can it be tapped and helicoiled? this is last thing to do before i fire my car up for the first time with the new cam and redone heads. my pcm will be in tomorrow and i would love to have the car ready for it.
