6.7 Powerstroke OE Crankcase Oil Separator Assembly – Ford DC3Z-6A785-C

Keep your 2011-2016 6.7L Powerstroke running cleaner and stronger with the genuine Ford DC3Z-6A785-C Crankcase Oil Separator Assembly (also called the CCV / Closed Crankcase Ventilation oil separator or oil/air separator).

This OE assembly is designed specifically for the early 6.7L Powerstroke. It efficiently separates oil mist and vapors from crankcase blow-by gases before they can re-enter the intake system. By doing so it reduces oil contamination, cuts down on sludge buildup, helps protect against corrosion, and minimizes excess ash loading on the DPF — all while maintaining proper crankcase pressure.

Key Features & Benefits

• Genuine Ford OE part (DC3Z-6A785-C) built to original specifications
• Built-in check valve helps prevent oil blow-by
• Includes sensor provision
• Direct-fit replacement that restores proper closed crankcase ventilation performance
• Helps maintain cleaner intake charge and more consistent engine efficiency
• Recommended as preventive maintenance (typically every 30,000–40,000 miles)

Vehicle Fitment

Fits 2011–2016 Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel:

Replaces earlier part numbers including BC3Z-6A785-A, BC3Z-6A785-B, BC3Z-6A785-C, BC3Z-6A785-EA, DC3Z-6A785-A, and DC3Z-6A785-B.

Genuine Ford quality with the hardware needed for a straightforward installation. A clogged or failed CCV is a common source of elevated crankcase pressure, oil residue in the intake, and related drivability issues on these engines — replacing it with the correct OE unit is one of the simplest ways to protect long-term reliability.
