  Q: What is the purpose of the Positive Crankcase Ventilation (PCV) system and PCV Valve during engine operation on Ford F-250?

  A: An oil mist is created when the crankcase is agitated by oil during engine operation. Positive Crankcase Ventilation (PCV) relieves pressure by venting vapors and gases into the intake manifold for combustion. The PCV valve has a mode of ventilation that allows small quantities to pass through at stop and large volumes under a higher load. An air filter is used to provide clean air which goes to the valve cover or can be connected via a dedicated hose. Such PCV systems are always equipped with a PCV valve, situated in the intake manifold or on top of the cylinder head cover, joining the two inlet manifolds using a vacuum hose. The PCV valve ensures optimal engine performance and emission control by regulating airflow and gas flow into the intake manifold.
