RHAOCZIYAUTO CCV Crankcase Vent Valve for Ford 6.7L Powerstroke — Black PA66 Nylon, OE Fit PC3Z-6A785-A

RHAOCZIYAUTO CCV Filter Engine Crankcase Vent Valve Air Oil Separator Assembly replaces the factory crankcase vent to separate oil from blow-by and reduce back pressure in compatible Ford 6.7L Powerstroke engines.

This replacement Air Oil Separator (AOS) is engineered for Ford Super Duty trucks with the 6.7L Powerstroke diesel and covers a wide range of model years. Built from PA66 nylon for heat and wear resistance, this CCV unit follows the OE footprint and replaces part numbers PC3Z-6A785-A / PC3Z6A785A. It improves crankcase ventilation flow and fits both modern and older model applications — note that later-model engines use a sensorless design while some earlier trucks may require a fault-code clear after installation.

How does this CCV assembly affect engine ventilation and back pressure?

The RHAOCZIYAUTO CCV Filter is designed with a revised crankcase layout that helps manage blow-by gases and reduce crankcase back pressure without changing engine performance. By separating oil from the vented air, it reduces oil carryover into intake systems and helps maintain cleaner intake components over time. The compact structural design also allows more efficient packaging within the engine bay.

• Direct replacement for OE part numbers PC3Z-6A785-A and PC3Z6A785A
• Separates oil from crankcase gases to limit oil migration
• Optimized flow pattern to lower crankcase back pressure
• Compact form helps tidy engine layout without performance loss

Which Ford models and years does this part fit?

This CCV vent assembly fits Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke diesel. Coverage spans recent model years (2023–2026) as well as earlier Powerstroke-equipped trucks from 2011 through 2022 when the compatible factory configuration is present. Always confirm fitment by comparing part numbers or vehicle-specific details before ordering.

• Compatible with Ford F-250, F-350, F-450, F-550 Super Duty
• Covers 6.7L Powerstroke trucks: 2011–2026 (verify specific model fit)
• Replaces PC3Z-6A785-A / PC3Z6A785A OEM parts
• Check sensor requirements for 2011–2016 models

What materials and durability can I expect from this replacement part?

The unit is molded from PA66 nylon, a high-strength polymer chosen for resistance to heat, wear and mechanical stress common in engine bays. That construction contributes to long service life and reliable operation under high-temperature diesel conditions. The design aims to maintain integrity while performing constant crankcase ventilation duties.

• Made from PA66 nylon for heat and wear resistance
• High mechanical strength for long-term durability
• Engineered to withstand diesel engine bay conditions
• Factory-style fit and finish for straightforward replacement

Are there installation notes or electronic considerations I should know?

Installation is a direct-replacement process if your vehicle uses the same mounting and hose layout as the original. Models produced after 2016 typically use a sensorless configuration, so this unit arrives without a sensor. For 2011–2016 trucks that originally had a sensor, install the part and clear any fault codes if they appear to restore normal system operation.

• Direct-fit replacement for matching OE configurations
• No sensor included — intended for sensorless late-model designs
• 2011–2016 vehicles with sensors may require fault-code clearing
• Follow typical torque and hose-seating practices on installation

Who is this for: This RHAOCZIYAUTO CCV Air Oil Separator suits owners and technicians of Ford Super Duty trucks with the 6.7L Powerstroke who need a reliable, OE-style crankcase vent replacement. It’s aimed at those upgrading or repairing ventilation components to reduce oil carryover, refresh aging plastic parts, or restore proper crankcase flow. If you need an aftermarket CCV that matches original part numbers and prioritizes durability, this assembly is designed for your truck.
