Broken piston. Likely a result of detonation.

Sounds like you blew it up. Do a compression test.

Oil generally doesnt rattle, anything else either gets chewed up, or spat out.

Make sure it didn't damage your turbine wheel. I had a spark plug loose the tip a couple years ago for some unknown reason and took out the turbine. Pistons looked perfect, no detonation, etc.
