Thanks guys. I actually did replace the bolt with a new one. I figured $6 was cheap peace of mind. Maybe I'll try to re-torque after a few heat cycles and see if it budges.

On another note, my oem crank pulley looks to have been balanced from the factory. They drilled out some spots of the outer ring. Do you think they were just balancing the pulley itself or is this to balance the whole crankshaft? I always thought the crankshaft was balanced internally on modern vehicles and didn't require pulley balancing to compensate...
