What does a broken ring look like?

[LettersFromFlyoverCountry]

Yeah, I think that makes a lot of sense. I think I'll do one more compression check and get another pair of ears to listen at the breather and then go fly.

My only other question -- and I forgot to ask Mike this -- is : I know what a symptom is from the pilot's seat of a stuck valve. But if there's a broken ring there somewhere, what is the symptom I should be looking for other than an increase in oil consumption and a lower compression ?

That is about it, Bob, you should not notice any performance issue, for a long time. Keep flying, virtually no risk, and retest in 10 hours.

Bob,

I sat through a Superior Air Part Compression testing seminar at Airventure in July. Just like many has said, the stars and ring gaps may have aligned. Just fly it for a few more hours and retest. Let us know if your compression has improved.
