Usually when all the rod bearings fail there has been a lubrication failure. Did you notice if the oil pressure gage was showing any pressure when the engine failed? Check the oil pump for failure. I would suspect a bad oil pump.

I broke the end of the oil pump shaft off one time and it ruined my rod bearings and not the mains. The rod bearings take more of a beating, they are smaller than the mains and they run out of oil before the mains.

About the oil on the outside of the engine, maybe a plug in the oil line system came out or the oil pressure regulator failed. You might plug all the oil holes and apply air pressure to one hole and see if you can find any leaks. Maybe the head gasket failed where the oil goes into the head to lubricate the cam.
