PCV System
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
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.
