Genuine Ford OEM 6.7L Powerstroke Crankcase Oil Separator / CCV Filter Assembly – FC3Z-6A785-F

Keep your 6.7L Power Stroke running clean and efficient with this genuine Ford crankcase oil separator assembly (also called the oil/air separator or CCV separator). Part number FC3Z-6A785-F is a direct-fit OEM component for the closed crankcase ventilation system.

Key Benefits

• Separates oil mist from crankcase vapors before they can enter the intake tract
• Helps reduce oil consumption and prevents oil buildup in the intercooler and charge-air system
• Maintains proper crankcase pressure and supports long-term engine health
• Direct OEM replacement — no modifications required
• Built to Ford’s factory specifications for durability under diesel operating conditions

Fitment

Fits 2016–2019 Ford Super Duty trucks equipped with the 6.7L Power Stroke diesel:

• F-250 Super Duty
• F-350 Super Duty
• F-450 Super Duty
• F-550 Super Duty

Primarily for single rear wheel (SRW) pickup applications. Always verify fitment with your VIN, as dual-rear-wheel and cab-and-chassis configurations can differ.

Replaces

• FC3Z-6A785-D
• FC3Z-6A785-E (and related earlier supersessions)

This is the complete oil separator assembly (not just a service filter element). A failing or clogged CCV separator can lead to increased oil consumption, oily intake components, and elevated crankcase pressure — replacing it with the correct OEM unit restores proper system function.
