Crank Pulley Came Loose

mults

A few questions come to mind:

1) Did the wobble disappear after the crank pulley was re-torqued?
2) I assume that the wobble is gone so, is there any noticeable vibration now?

If the wobble is gone and there is no discernible vibration, I would say that you got lucky that there is no lasting effects from the loose pulley.

Pulleys have a pretty tight fit, so even if the bolt loosened up along the way, it would have taken some time for the pulley to move on the crankshaft. I wouldn't be so worried about the engine, but I would replace the belt for sure and while the belt is off, make sure that anything the belt rode on (tensioner, alternator, etc.) still turns easily and that there is no damage to any of the bearings in these components.

Keep up posted as to what you find...
