Air Oil Separator Assembly Compatible with Ford F250 F350 Super Duty 2023-2024 OR 2011+ 6.7L Powerstroke Diesel Replace# PC3Z-6A785-A PC3Z6A785A

Description

Product Overview

The Jaeparbus air oil separator assembly is engineered specifically for Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine. It replaces the OEM part number PC3Z-6A785-A and integrates seamlessly into the factory‑mounted location, ensuring that oil mist generated by the high‑pressure fuel system is captured before it can enter the intake manifold. By eliminating oil vapor, the separator helps maintain optimal combustion efficiency, reduces carbon buildup on the intake valves, and extends the life of downstream components such as the turbocharger and intercooler.

Constructed from a high‑temperature PA66 composite material, the unit offers industrial‑grade durability that outperforms traditional plastic separators. The composite resists heat soak, vibration, and warping even under the extreme conditions typical of heavy‑duty towing, off‑road work, and prolonged high‑rpm operation. Reinforced welds and precision‑machined ports provide a leak‑free seal, while the corrosion‑resistant finish protects the body from moisture and road salt exposure.

Inside the separator, a multi‑stage oil separation system utilizes internal baffles and a check‑valve style vent to create a series of turbulence zones. These zones encourage oil droplets to coalesce and settle into the collection chamber, while a back‑flow control valve prevents blow‑by vapor from re‑entering the intake. The result is a consistently clean air stream that supports better fuel atomization and more efficient power delivery.

The design incorporates reinforced hose barb adapters that match the original factory connections, eliminating the need for custom fittings. All sealing surfaces have been re‑engineered with improved gasket materials to ensure a tight, leak‑free fit. The unit weighs only 1.6 pounds and measures 19.5 x 6.4 x 6.4 inches, making it compact enough to fit within the existing engine bay without any modifications to surrounding components.

Each package includes the complete diesel air oil separator assembly, a set of high‑quality gaskets, and replacement hose connections. Installation requires only standard hand tools and can be completed in a typical service interval without the need for ECU re‑programming or special calibration. The result is a plug‑and‑play upgrade that delivers immediate performance benefits and long‑term reliability.

Usage

This separator is ideal for daily drivers, fleet vehicles, and heavy‑duty work trucks that operate in demanding environments such as construction sites, farms, and long‑haul routes. By capturing oil mist before it reaches the intake, the unit helps maintain clean combustion chambers even when the engine is subjected to high loads, frequent stop‑and‑go traffic, or dusty conditions.

Owners who frequently tow trailers, operate in off‑road terrain, or run their trucks in extreme temperatures will notice a reduction in engine deposits and a smoother idle. The separator also benefits vehicles that run on low‑quality fuel, as it mitigates the additional contaminants that can be introduced into the air intake system.

Because the assembly is a direct replacement for the OEM part, it can be installed during routine maintenance, such as oil changes or filter replacements, without requiring additional downtime. The plug‑and‑play nature of the design means mechanics can complete the swap in under an hour, allowing the vehicle to return to service quickly.

FAQ

Is this separator compatible with all 6.7L Powerstroke models?

Yes, the part number PC3Z-6A785-A is a direct replacement for the OEM air oil separator used in 2011+ Ford Super Duty trucks with the 6.7L Powerstroke engine, covering model years 2023‑2024 and earlier.

Do I need any special tools to install the separator?

No special tools are required. The unit mounts in the factory location using standard hand tools, and all necessary gaskets and hose adapters are included in the package.

Will the installation affect my vehicle’s warranty?

Because the separator is an OEM‑equivalent part and installs without modifying any electronic control modules, it does not void the vehicle’s factory warranty when installed according to the manufacturer’s guidelines.

How often should the separator be inspected or replaced?

We recommend inspecting the separator during regular maintenance intervals, such as every 30,000 miles or during major service events. Replacement is typically needed only if the internal oil collection chamber becomes saturated or if physical damage is observed.

Can the separator be used on other diesel engines?

The design is optimized for Ford Super Duty 6.7L Powerstroke applications. While the unit may physically fit on other diesel platforms, we advise confirming fitment and performance specifications with the vehicle manufacturer before installation.
