These motors aren't that bad $$ wise at all to rebuild now that good quality aftermarket parts have been sourced.

The thing is that it appears the bearing did spin. I agree that replacing all the associated parts isn't that expensive. I'm just worried about the time and money needed to pull the engine (I can't imagine it's cheap). I do have the luxury of having the option to do the work myself but I just lack an abundance of free time to do so.
