yes you can remove the rotor / gears , and strip the pump for ispection, would have to be realy sure there is no bits left, should be clean as the course strainer in the sump shjould catch most bits before going to the pump, Jim i know some people have just replaced the conrod bearings, as long as the conrods, or crankshaft , werent damaged , cleaned out the sump, used a flushing oil, then replaced the oil, and the cars been fine without striping anything else,
