CHamber isolation ?

[Espen Hilde]

I think a turbo engine could have better durability at boost if the 
pressure in crankcase could have the same pressure as boost.
Think how the exhaust valve guides have a constant high back pressure
of hot exhaust.I canot imagine much lubrication can find its way down 
the valve stem .Allso the piston and rings with maybe higher air pressure 
on top of piston all the time .
