waqar Posted June 1, 2011 Report Share Posted June 1, 2011 Under the hood, center, upper engine area, mounted in PCV hose, located between the crankcase breather chamber and intake manifold. A crankcase ventilation system is a way for gases to escape in a controlled manner from the crankcase. A common type of such system is a positive crankcase ventilation (PCV) system, the heart of which is a PCV valve—a variable-restriction valve that can react to changing pressure values and intermittently allow the passage of the gases to their intended destination (which nowadays is the engine's intake stream).
