Any mechanics with some free time? Please take a look at my issue.

I believe cylinder 2 is toast. The other 3 coils looked fine, but after recently turning 200k miles. I’m not sure if they are since they’ve never been replaced. & After looking at these pics there’s probably a piece of metal bouncing around in there.

Plug 2 definitely wasn’t making a spark. With the missing piece still inside, Is this even fixable? Did the previous owner never change the oil?

Thanks in advance for any help you can give.
