So I’m sad to say that my #2 cylinder has (sorry if my terminology is incorrect) a broken tappet, oil seal, and cotter valve. The spring is still intact. I’ll post some pictures for reference."When you mean checking every part of the chain, are you referring to the cam chain? Am I to see if the chain has jumped a tooth, or if it has jumped off track?"
I was referring to the cam chain but thinking along the lines of a tight link in the drive chain, something that shouldn't happen to a cam chain. It sounded like something was getting wacked every revolution instead of a more constant rattling. Jumping off the track in the chain guide would be a possibility. With the upper chain guide off you could look for damage to its underside as well as inspecting the chain as you manually rotate the engine. A jumped tooth is certainly a possibility but it would affect every cylinder. Note that I may be making too much of the noise in your first video but that's what I heard - or thought I heard.
