If it shot a rod (which is appears to have done from all the oil), it appears to be a rod bearing failure.

The DME would reveal all of these conditions as it "records" the last xx seconds of operation. I would THINK if they did not warranty the engine 100%, they would have some reason behind it. If it happened to me, I would make damn sure they had proof if was my fault and not a mechanical break-down of some sort (oil pump failure, rod bearing failure, etc.).
Ya - EXACTLY
If they were making ME pay 50% of a $20k+ Engine -- I would want to see MAJOR PROOF of my mishap.
OP -- what did BMW show you, that made you say: "OK I'll pay the 50% of the engine, since I did fk it up"??????????
