I totally understand gapless top ring - but since their conception (seemingly a few eons ago) I've never been able to wrap my little pea brain around any benefit (just negatives) to a gapless second ring. What am I missing for benefits or possible benefits of gapless second ?

Gapless second rings came from when the gapless tops started getting thinner, but they didn't have the material technology to stand up to the heat and abuse. They then started moving the gapless ring to #2 but since then, ring technology has come a long way the the gapless 2nd is a thing of the past. With a gapless 2nd, all the top ring does is protect the 2nd...it can't do much for compression.

Very typical to see that on the ex side of the piston. That's where all the heat is and where all the gasses concentrate on the ex stroke. Any un-burnt fuel and oil will accumulate there and get baked on the piston. Engine was sealed up nicely.

^^^^ that answers my question, thanx.
You can see there`s a bit of scuffing on the skirt, that is also on most pistons even on the "good" motor. Thoughts on that?

if you can,t feel the scuffing with your finger nail it is nothing to worry about.

Is that from piston slap?
