Wow, that must have been frustrating after putting a low mileage engine in to have to take it back out for a new crankshaft. Looking over the damage to mine, I don't think that the car was even being driven when the damage occurred. My guess is that a pickup truck backed up into it just above the bumper bar. Watching it run, it appears that the inner crank pulley is smooth on the axis and the outer part of the pulley is where it wobbles. Hoping for the best and waiting for confirmation that the title is on the way for the body-donor before I start moving the engine.
