That looks like a teensy grenade went off in there.

Dropped valve, T7 cylinder head.
So I was speaking with some people and heard some rumors of dropped valves, as well as pitting on the exhaust valves and seats. Well I semi-recently dropped a valve, and have witnessed three instances. Two on early 9-5's, and one on a Viggen. This is all out of a 9-5, the picture quality is terrible as it is from my ipod. But there are pictures of the combustion chamber (practicing porting that is why there is metal shavings). Piston that the valve contacted, the stem and head of the valve that broke and any other affected parts.
Pitting on the valve face (exhaust only, all of them not only in the cylinder that the valve let go in).
Just wanted to show some proof, for any doubters. I have seen three instances since working at the dealer, and experienced one personally. At 100,000~ miles.
