Baffled 3 Port Oil Catch Can Tank Air Oil Separator With Removable Valve 3-hole Oil Kettle. The oil catch tank collects such oil mist and condenses the fuel vapors while allowing cleaner gases to be passed back into the intake. An oil catch tank is used in turbo applications, or high-performance racing applications where excessive blow-by (leakage past the piston rings) of air and fuel vapor occurs. Crafted from high-strength plastic, this Oil Separator Segregator boasts resistance to corrosion, wear, high temperatures, and rust, along with dependable quality and outstanding performance. Serving as a fuel pretreatment component, the cylinder oil separator breather valve efficiently eliminates water and contaminants from fuel, stopping these substances from corroding and abrading fuel system and engine parts., Manufacturer: ZTAWWCJ
