PC3Z-6A785-A CCV Oil Air Separator for Ford 6.7L Powerstroke 2011-2026

CCV FiltersCE / ISO 9001

The PC3Z-6A785-A oil/air separator is the closed crankcase ventilation (CCV) assembly for 2011-2026 Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke diesel. The baffle and check-valve housing separates oil mist from blow-by gas before that gas returns to the turbo inlet. Direct bolt-on to the driver-side valve cover; not for cab-and-chassis models.

❓ FAQ

Yes. It fits 2011-2026 F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke diesel, as long as the truck is not a cab-and-chassis model. Ford designed this revision for 2023-2026 production and it is also the current service replacement for earlier trucks, so on a 2011-2022 vehicle it is an upgrade from the older filter-box style unit rather than a like-for-like swap.

No. The PC3Z-6A785-A covers standard F-Series Super Duty pickups and standard-frame trucks only. Cab-and-chassis (chassis cab) applications and F-650 / F-750 use different assemblies, so confirm by VIN before ordering for those builds.

This is the complete assembly: housing, baffle stack and check valve, with no serviceable internal element. The element-only part is GC4Z-6A777-B, which serves 2017-2019 dual-rear-wheel trucks that already have the GC4Z-6A785-D housing. The two parts do not substitute for each other.

On 2011-2016 trucks that use a CCV sensor, clear the related crankcase ventilation codes after fitting. On later sensor-less builds the assembly is plug-and-play and needs no programming or relearn.

Typical signs are a hissing or dancing oil filler cap, oil weeping around the separator and its hoses, oil residue at the turbo inlet, an oily film inside the charge-air tube, and a P04DB code. Check that the fresh-air quick-connect is fully locked before replacing the assembly, because a partly seated joint produces the same code.

Description

Product Overview

The PC3Z-6A785-A is the closed crankcase ventilation (CCV) oil/air separator assembly for 2011-2026 Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke V8 diesel. It installs on the driver-side valve cover using the factory bolt pattern and the original quick-connect fitting, and needs no programming. The housing is a baffle-and-check-valve design with no serviceable internal element, so the complete assembly is replaced as one part instead of being re-cored. Cab-and-chassis models are outside this fitment.

Key Features

Factory mounting — Original bolt pattern and CCV quick-connect, so the old unit comes off and the new one goes on without adapting brackets, hoses or wiring.
Baffle and check-valve separation — Blow-by gas passes a fixed baffle stack and a one-way valve. There is no element to seat the wrong way round, which removes the mis-assembly risk that comes with serviceable cartridges.
Heat-resistant engineering plastic housing — Holds its shape under sustained oil temperature, vibration and continuous oil immersion.
Pre-assembled unit — Ships complete with seals fitted; valve-cover service needs no special tools.
Sensor provision kept — The 2023-and-later CCV connection sensor port is retained, and the knockout tap plus bolt hole allow fitment of an aftermarket crankcase pressure sensor where the truck uses one.
Item weight 1.49 lb (0.68 kg) — Light enough for one-person handling during valve-cover work.

What a restricted separator looks like on the truck. A blocked CCV path raises crankcase pressure. The visible symptoms are a hissing or dancing oil filler cap, oil weeping around the separator and its hoses, oil residue at the turbo inlet, an oily film inside the charge-air tube, and a P04DB crankcase-ventilation-disconnected code. On an engine that has run restricted for a long period, oil reaching the intake also adds to DPF ash loading, so DPF condition is worth checking at the same service.

Element-only part, not a full assembly: GC4Z-6A777-B is the crankcase oil separator filter element for 2017-2019 dual-rear-wheel trucks that already run the GC4Z-6A785-D housing. It does not replace this assembly, and this assembly does not replace it.
