Did a test a while back just to verify the presence of a vacuum in the crankcase.

The intention of the system is to prevent crankcase blow-by gasses from entering the atmosphere.
If it were bad for the engine the manufacturers would not be installing them on cars.

The primary function of the PCV valve is to close off the back flow to the crankcase in the event of a back fire. Not to regulate flow.

Would like to see the stock road draft tube setup that created any vacuum.
