The butt cut used in automotive applications is least effective. a step cut or sure-seal joint for the piston ring is better. The tri-lap seal is used for steam.

yes; much hyperbole.

Only a very small amount of the water formed during combustion will get past the piston rings on each power (and exhaust) stroke.
But in my defense; there are a good many power strokes in the average commute.
A 4 cylinder engine at say 4000 rpm has 4000 a minute, or 240 000 an hour.
Then there's condensation and bigger ring gaps in cold engines and all that.

I'll look through these later, but we both know that the water and thus acids formed in an engine sump is an issue.
Nice to turn it to an advantage in this case...
