Blown piston? or valve smashed into piston?
When it arrived on the back of the truck it was sitting on its bump stops and I wasn't game to start the engine as the coolant reservoir was empty (and I mean completely empty and missing its cap) plus the second from the front on the right hand side of the engine spark plug and ignition coil had been removed, and this is what I could see using a small camera.

What do you think? blown piston? or is that valve material melted / squashed in there?
Thanks.
