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. Constructed with high-strength plastic, this Oil Separator Segregator is resistant to corrosion, abrasion, extreme heat, and rust, delivering consistent quality and excellent operational performance. The cylinder oil separator breather valve functions as a fuel pre-processing device, efficiently removing water and foreign particles from fuel and protecting the fuel system and engine components from corrosion and wear induced by these contaminants., Manufacturer: KVSWBRE
