I can't believe that the skirt on the piston is broke when it was never really ran.
Are you sure the correct pistons were installed in that engine? Seems like the skirt may have been smacking the crank on the down stroke to do that kind of damage.
It had steam b4 carnage. He shut it down overnight and started it again and then it went south. Could have had a cylinder full of water and broke the piston pin boss when it came up on compression. Water dont compress and either head gaskets blowing,rods bending or pistons breaking.
