You can see where the valve heads pounded a hole through the piston. That’s where the oil in the intake system came from.
Note the big cracks in the cylinder wall. I’m guessing that was caused by the piston getting cockeyed while pound the valves into oblivion. That’s where the water in the intake system came from.
So…. the block is a total loss too.
Time to start looking for a new engine. Bah!
