As if this weren't enough, the adjacent rod journal is out of round (min: 50.6mm max:52.0mm).
Motor did not spin any bearings but the two in question were well worn into the copper (2008 model year). What's the max tolerance for out of round journals and how does this happen? I guess there's no visual scratches. Shop thinks I need to pull the motor and find a new one.

Did they break a bolt off? Very odd. Good luck.
