Where does he have the PCV valve at and where is it connected? If you have the PCV valve in a valve cover (or like the Cobra does, in the lower intake direct to the valley of the block) with the other end connected to the intake manifold vacuum then if you gut the PCV valve you will push boost into the crankcase.

Valve cover, his isnt gutted so it closes when there is boost. I think he might have an intake suction tube also though.

And in the VETTE its not connected to vacuum, its in front of the blower, only suction all the time.

Its too much crankcase pressure, need to fix the underlying issue. Head is already being replaced. Was trying to see if re-ringing was also a good idea, or unwarranted

Excessive crankcase pressure comes from either a blown head gasket or bad rings/ring seal. Somehow the cylinder pressure is escaping.

Either that or the PCV system isn't working at all. Maybe gunked up lines, or even the PCV itself is gunked up.
