Not if there's no air flow through the "baffled" grommets.

Kinda guessing this system brings crankcase fumes to the air cleaner (carb vacuum) rather than the intake manifold (manifold vacuum).

If this directs fumes to manifold vacuum, I suppose it relies on a restrictor orifice like some of the LS engines are using in lieu of a PCV valve.
