Description
Upgrade your crankcase ventilation system with the 034Motorsport Valve Cover Breather Adapter, engineered to deliver a robust and permanent solution for eliminating the factory oil separator and PCV assembly in your 2.0 TFSI or TSI engine. Constructed with internally-channeled precision and outfitted with dual -10AN fittings, this adapter allows for seamless integration with your preferred catch can setup, ensuring optimal oil vapor management, improved reliability, and a cleaner intake tract.
This breather adapter addresses the well-documented failure points of the OEM system, which often leads to oil ingestion, boost leaks, and long-term carbon buildup in the intake manifold. By eliminating the PCV assembly and rerouting vapors through a catch can, this solution enhances long-term engine health and supports higher boost levels in modified setups. The adapter connects directly to the OEM breather hose that leads to the turbo inlet and removes the breather provision on the intake manifold — a frequent source of boost pressure leaks on factory setups.
Whether you're tracking your vehicle or looking for improved long-term reliability, this is an essential upgrade for enthusiasts aiming to eliminate one of the most common reliability issues in the 2.0 TFSI/TSI engine family.
Key Features:
-
Replaces Factory PCV & Oil Separator – Eliminates failure-prone OEM oil separator (OEM Part #: 06H 103 495E).
-
-10AN Catch Can Compatibility – Allows for flexible catch can installation using -10AN fittings.
-
Internally Channeled Construction – Promotes efficient and unrestricted vapor flow for optimized crankcase ventilation.
-
Boost Leak Prevention – Removes the manifold breather connection, eliminating a known source of boost loss.
-
Carbon Buildup Reduction – Prevents oil from recirculating into the intake manifold, reducing intake valve carbon deposits.
-
Precision Fitment – Designed for direct connection to the OEM breather hose for a clean, secure installation.
-
Built for Durability – CNC-machined from high-quality materials for long-lasting performance under demanding conditions.
