A lot of oil in those cylinders, and what looks like scuffing on the cylinder walls, especially #2.

Can't be sure about the cylinder wall finish.

I run about 8# tangential tension on the oil rings, with a Speed Pro oil ring package, and Napier cut second rings. I do not run zero gap rings, but I do run Total Seal Advantage rings. The finish is absoultely critical, as is the bore being round.
