I hit **** with sticks!
Hmmm, some interesting impact damage there. Hopefully the mayhem didnt crack the head or any of the pistons. The damage in the one cylinder is from the chunk of valve that is missing. Looks like it bounced around in there a bit. How does the top of the pistons look? Check the turbo. I know you said the tensioner failed, but just check to be sure no turbo blades got inhaled into the engine instead.
