Does this 5.9 Magnum look ok?

The tabs are called tattle tails and are epoxied to heads/engine so they can tell if you overheated the engine. They say LKQ on them, a nationwide wrecking yard....it was a used engine sold by them. The #8 piston is horribly carbon fouled which could mean bad guide seals or rings but based on the amount of oil, I would guess it had a bad belly pan gasket, allowing vacuum to suck oil into intake annd pool in rear of pan. There appears to be some form of detonation on that cylinder from carbon turning into a briquette stuck to cylinder. If the big one is carbon, scrape it off, if its aluminum, use dremel to sand it flat. Might want to pull that one and look for cracks in piston and oil below rings. With that much detonation, you might have a broken ring as well. Other than that, it doesnt look out of ordinary at all
