Time for the engine builders to chime in.

Gotta Pay To Play
Pulled a motor from the yard today, Ran when I pulled it.
Started taking it apart for a rebuild and found something weird, The first two are the "damaged" pistons...the last is a non "damaged" one.....

Any ideas on why or how this happened, Obviously it wasn't that bad to kill the engine....Just seems weird. Only thing I could even imagine is that it had a bad injector or plug and was detonating pretty bad.Its just that the markings are so odd looking.
