I might have messed up the first thread or two when I was removing my timing gear. I used the wrong puller and I think that I messed up my first couple of threads. I am having trouble starting the harmonic balancer bolt. I do not want to force it at all. Any ideas of how to clean them up? would a thread chaser (not tap) be the possible solution? I just do not want to make it worse. The engine is still out of car.
