I started taking things apart today and I knew it was going to be bad when I removed the valley pan to see that the camshaft had broken into 3 pieces and one part is wedging the crank. I also noticed pieces of piston and rings up in the valley cover. Not good.
When I took the drivers head off, I saw that the #5 exhaust valve had broken (factory 2 piece valve I'm assuming?) It seems that when it came apart that the piston completly obliterated from the rpm's I was turning at the time, and all the coolant came in because the wrist pin dug a hole in the bore.
Complete destruction of the block. Looks like I'll be in the market for a new engine.
Picture 1 shows the broken camshaft
Pic 2 shows the valve head missing. (chunk of metal above the chamber is a piece of the piston that was stuck where the valve should have been)
Picture 3 shows how none of the piston was left on the pin.
