Product Information
Upgrade your failure-prone PCV breather hose with the high-performance, 034Motorsport Catch Can Kit, engineered for enhanced durability to capture crankcase oil deposits before entering your intake tract.
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 034Motorsport Catch Can was engineered to improve upon the factory PCV system, implementing a baffled Billet Aluminum Catch Can to trap crankcase oil deposits before entering your intake tract. The Catch Can Kit utilizes a re-engineered breather hose that plays an integral role in this ventilation system.
How Does the PCV System Operate? 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. This system operates with two components, an Air Oil Separator and a Breather Hose.
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. During this state, the breather hose utilizes this vacuum to release crankcase pressure into the charge air system through the connection just after the throttle body.
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. When this happens, a check valve in the breather hose closes off this connection, preventing boost pressure from entering the crankcase. At this point, the breather hose is able to draw vacuum from the turbo inlet connection, as this creates vacuum through a siphoning effect as the turbocharger draws air in through the intake.
Whether you are sitting at a stoplight or romping on a backroad, a properly operating PCV system is crucial for maintaining the engine’s performance and preventing harmful pressure buildup.
