Probably wouldn't cost all that much to have Savvy Analysis review the issue.

And here's a webinar he put on about the subject:

All the additional tests are not going to correct that cyl. Scoring and damage.

Puts some Marvel Mystery Oil in the oil and gas and fly it a couple hours around the airport and then check it again.Works every time.

Will it fix a broken ring?

Its pretty simple, cut the filter open and have a look at it and the sump screen, if they are clean borescope it. If that's negative fly a pattern or two and recheck. If it's still down it's not gonna improve and you need to pull it. Flying it without knowing why it's down is asking for it.
