We've also got cylinders reading 63, 68, 70, and 73.
If one dips down, do we just top the whole thing (it has about 1800 tach

I think it depends on what is wrong with the "bad" jug. If it has no cracks

pulled the jug, sent it out for repair, and flew on it with no preblems for
the next 300 hours, until general engine condition (and calendar time SMOH)
dictated a major,
