Odd Sleeve Damage
Hello all, my first post here, been a long time lurker and finally found something worth a post.
So today I finally got around to pulling the heads on my junkyard L33 and I found this beaut!
This big pit just above the top ring and below the deck showed itself. I'm puzzled of what may have caused it. There is no other damage to the bore, head or piston.
My intentions were to gap the rings and let er eat but now I'm worried this may cause spontaneous premature engine disassembly under boost. It's too deep to bore out so re sleeve? Or just run it and hope for the best.
I got the whole engine from the yard for 600 Canukistan Copecs so it's not a huge loss but the aluminum blocks are a tough find up here. I'd like to save without turning over my first born to the machine shop. Thoughts?

Just kidding (or maybe I'm not!). It doesn't seem to extend into the ring area, so I don't think it will hurt anything.
I, too, am curious as to how that happened. Detonation is the only thing I can think of; you should probably go over that thing with a fine-toothed comb for other damage.
