The oil separator is a critical component of the crankcase ventilation system. It separates oil mist from blow-by gases before they are recirculated into the intake. A worn or failed separator can lead to increased oil consumption, reduced engine performance, and failed emissions testing. Replacing both units simultaneously with this complete set ensures the system is fully restored.
