Re: defining "rebuilt"
Folks seem to often sell right after a rebuild which makes me think they lack confidence in the quality durability of what they've done. I'd actually want it to have some run time. In discussing their work I'd be listening for tell tale signs of competence. Torque wrench, loctite, photographs, micrometer measurements, new parts even where old ones may have some life in them such as a water pump or alternator. Short cuts less likely if they thought they were going to keep her. Amazing how many people advertise they've freshened or "redone" their motor. I doubt anyone doing a professional job will lack receipts or photos documenting just how much was "redone". To me lacking the depth of knowledge to discuss particulars would be a red flag. Good luck. There ARE competent and honest folks out there.
