Own a 2011–2016 Ford Super Duty with the 6.7L Powerstroke diesel? This oil separator assembly helps keep your engine running clean. It replaces the factory PCV/CCV valve (part DC3Z-6A785-C) and works on F-250, F-350, F-450, and F-550 models. By catching oil vapors from the crankcase ventilation system, it reduces carbon buildup in the intake and turbo, which can improve performance and longevity. Easy to install with basic tools – comes with all necessary hardware. Most DIYers can swap it in under an hour. Regular maintenance (check every 10,000 miles) helps ensure your engine breathes cleanly. This OEM-style unit is plug-and-play, so no modifications needed. Helps prevent oil consumption issues and lowers emissions, too. A smart, affordable upgrade for diesel owners who want to protect their investment. Keep your Powerstroke running strong – add this oil separator to your maintenance routine.
