ive done 3 motors, which doesnt make me any kind of expert what so ever...but I have used the same crank bolt 2 out of three time and never have any issues. The second time I used the GM bolt I used red loctite though. I was too cheap to go by a new bolt when the old bolt only had 400 miles on it

and as for swapping a crank while the motor is in a vehicle (any vehicle) no way! I'll pay to see this done and done correctly. Its to easy to pull the motor and put it on a stand

Well ended up picking up a new crank for $125. Got new main and rod bearings also. Should have it swapped in the next couple weeks.

What do you heat up? the balancer or the end of the crankshaft?
