I Forgot about this thread, Aliens did not cause the breakage. It was a broken oil pump shaft which was likely caused by debris in the oil pump. Posted some of the engine internals at
Photos at GTSparkPlugs
Scroll down to the middle of the page you can see some of the problems, but so far 2 broken valve springs, 1 bent valve, broken oil pump shaft, clean oil, but some small metal (aluminum) chunks. Have to yank the engine to see what the chunks are, but likely broken piston bits.
I posted more of the videos on the
Motorator just search for "The Ripper"
