Re: To PCV or not to PCV

Stephan,

One side of the PCV system is the fresh air input and doesn't need a valve. 
After passing through the air filter, clean air is sucked into the crankcase 
and then sucked out the side with the PCV valve using manifold vacuum. The 
amount of blowby is typically small so it won't blow out the side with no valve.
