Excess Crankcase Pressure

I can point to tons if info that show you pcv does indeed aid in ring sealing. But what's the point? lol

Just remember, it all depends on WHAT you're talkin about.

Well the point would be you can't explain a PCV valve sealing the piston rings more.

More accurate statement would be evacuating the crankcase pressure could possibly relieve some of the blow-by or oil burning. It absolutely does not seal the piston rings more though.
