Nismo Oil Separator - Nissan Skyline GT-R R33 R34 RB26DETT

The Nismo R34 Oil Separator Kit is a performance-enhancing component designed specifically for the Nissan Skyline R34 GT-R. Its primary function is to efficiently separate oil from the blow-by gases in the engine's crankcase, preventing oil from entering the intake system.  

​This kit typically includes a high-quality aluminum oil catch tank, often with multiple ports for optimal routing, and a selection of durable hoses and fittings. The catch tank itself is designed to effectively condense oil vapor, allowing the oil to collect at the bottom while cleaner air is recirculated or vented.
