[QUOTE="Fred W, post: 537794, member: 3828"] My concern if the ring seal is the culprit, which your wet compression test says is the case, would be that the ceramic composite cylinder coating would be compromised. Can't just re-bore like an old cast iron cylinder. This has certainly been bad for you OCfjr, but the good news is we don't hear about this all the time. The theory about leakage of unfiltered air makes a lot of sense. [/QUOTE]
