PCV System
The PCV system
- uses intake manifold vacuum to ventilate blow-by gases from the crankcase.
- returns the gases to the intake manifold for combustion.
The PCV valve
- varies the amount of blow-by gases returned to the intake manifold based on available engine vacuum.
- is integral to the LH valve cover.
