Fitment information

Application

The PCV, or Positive Crankcase Ventilation system, on the EA839 is located on bank 2 of the engine (The right side of the engine).; It is designed to ventilate the engine's positive crankcase pressure through a breather hose into the intake tract or charge air system.; The Positive Crankcase Ventilation System, or PCV for short, works to remove excess pressure from the crankcase system and relies on vacuum from the engine’s intake system to operate properly.; In the EA839, crankcase pressure is generated by the engine rotating assembly moving under normal operation, and can contain oil in the form of liquid & vapor, water vapor from condensation, and blow-by gases.; The Air Oil Separator acts as a collection chamber for this crankcase pressure and oil, separating some, but not all of the oil and water vapor, allowing the oil to drain back into the engine oil pan.; The crankcase pressure not caught in this chamber is evacuated through the breather hose to be ingested by the engine.; At idle or cruising while not in boost, the engine’s charge air system operates under vacuum, drawing air in continuously.; However, when the vehicle is under boost (during acceleration), this connection becomes pressurized, meaning it can no longer provide a vacuum source for crankcase ventilation.
