That's your hypereutectic whatsowhosis after 3k miles with some detonation that you've never seen or heard (with a UTEC knock detection and TUNA det mic.) Oh, and never below 96 octane.

I can't figure it out.

No, those are OEM. I don't know why but I saw the hairline cracks and left it at that. Last night I figured I'd pull the rings to inspect them (they were 100% ok) but a couple of chunks of aluminum sort of fell off.
