Not sure i can save this slant 6
Looks like a Comp Cams 264 S cam. I don't have personal experiance with that cam, but have heard of problems with oil pump gear/cam problems. That is what the pictures show. Wiped out oil pump gear and cam gear. If it had a high volumm oil pump that makes matters even worse, as it puts more load on the gears. Gears fail, pump stops pumping, bearings fail. Not saying the body shop didn't "play" with it. Not likely to have a rod go away like that, just moving the car around.
