034Motorpsort's billet PCV check valve serves as a simple, elegant, indestructible replacement for the problematic OEM Audi/Volkswagen plastic valve (035 103 245A).
The 034 check valve is a high quality spring-loaded ball-style unit designed for simple bolt-on installation for the Audi AAN I5 20VT, Audi/Seat/Volkswagen 1.8T, Audi 2.7T, and many others. Features a CNC-machined billet aluminum housing with stainless steel ball-bearing and spring.
Can also be used in universal applications where you'd want to keep pressure out a specific hose or chamber, pressure side features a 1/2" nipple, vacuum side a 1" OD. Suitable for applications up to 100PSI or more.
Fitment:
*Fits other VAG models including early VW Rabbit/Scirocco, Audi 200 20v, etc. Can be used universally in any application where a similarly-sized ball-style check valve is needed.
