Air Oil Separator Assembly PC3Z-6A785-A PC3Z6A785A Replacement for F-250 F-350 F-450 F-550 Super Duty 6.7L Powerstroke Diesel 2023–2024 Crankcase Vent Oil Separator PC3Q-6A785-AB

Product Function The separator plays a critical role in the engine’s ventilation system by separating oil droplets from blow-by gases before gases are routed back into the intake path. Proper separation helps reduce oil accumulation in intake components and supports stable engine operation.  Material & Construction Manufactured using engine-grade plastic housing and internal separation components, this unit is designed to withstand: High engine bay temperatures Continuous oil vapor exposure Pressure fluctuations during normal operation The structure is optimized for durability and consistent performance.  Package Contents 1 × Air Oil Separator Assembly  Installation Information This unit is designed as a direct replacement for the existing oil separator assembly.  Typical installation steps include: Allow engine to cool completely Disconnect ventilation hoses from the existing separator Disconnect the old unit Install the replacement separator in the same orientation Secure all connections and check for leaks Professional installation is recommended for users unfamiliar with diesel engine ventilation systems.  Important Notes Confirm vehicle year, engine size, and part number compatibility before ordering Proper installation is required to ensure correct crankcase ventilation performance
