That made absolutely no sense....lets break it down:

there is no such thing as blow by in the cylinders....the blow by is in the crank case....caused by cylinder pressure getting past the rings.

High miles do not cause blow by, pressure and a nonfuntioning seal causes blow by.

Pistons have nothing to do with blow by, pistons do not seal the combuston chamber, the next component does...

Rings cause blow by. Not just any ring, but the lower compression ring causes blow by, not the upper compression ring, not the oil control ring....

And to top it off, blow by causes contaminated oil, which causes things like failed turbo bearings, spun rod bearings, and wiped cam lobes.

So where in that did you decide that more blow by gasses determine weather a piston is appropreate for high pressure and heat applications?
