Well right after I started ordering parts and getting ready to fix my jeep it started having a random knock. There isn't any rhythm to the knock but it is there (https://photos.app.goo.gl/dUmFBhvaNWBpRs1dA) video clip if it works, it's the loud knock that happens occasionally. Once that happened I parked it and took the oil filter apart and discovered metal in it as well as in the oil. I doubt anyone here will know anything more than I have figured out(which is just that something went and broke) but if you guys have any thoughts, I'd appreciate it, but from what it sounds like the repair bill for this isn't gonna be worth it anymore as now I'm looking at a new engine/total rebuild instead of just the top end.

Right now it sounds like the end of my liberty and it is most likely gonna end up being parted out, but I'm open to any thoughts/ideas but with how much work this suddenly turned into, it seems like a stretch.

The knock was also accompanied by a constant misfire on cylinder 6, it's been doing it for a bit just from the head gasket, but now it is constant(flashing engine light)

Sounds like a misfire, along with the tapping, noise is very top end so I wouldn't condem it just yet, definitely time to pull the heads though!
I wouldn't drive it until this is sorted because it will wipe the oil pump out & them it is game over for the engine.
If I was doing it I'd strip the top and assess the condition of the engine before buying any parts but at the moment I'd guess it's a lifter / rocker issue.
