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 the breather hose into the intake tract or charge air system.; The Positive Crankcase Ventilation System on the EA839 works to remove excess pressure from the crankcase system and relies on the vacuum from the engine’s intake system to operate properly.; 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.; 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.; These silicone hoses are molded to allow the factory engine cover to be utilized with the 034Motorsport Catch Can Kit installed.; Features: Direct Replacement of the Failure Prone OE PCV Hose Ensures High Flow Crankcase Ventilation to Prevent Crankcase Pressurization Eliminates Potential Boost Leak at OE Plastic Check Valve Housing Supports Boost Pressures to 40+ PSI Compatible with OEM and Upgraded Turbocharger Inlets CNC-Machined, Billet Aluminum Check Valve Body (Black Anodized), with a Heat and Chemical Resistant, Durable Rubber Diaphragm 4-Ply, Reinforced, Silicone Hose Retains Factory Engine Cover Simple Installation; Audi
