## At a glance

- The listing identifies PC3Z-6A785-A as the replacement reference and describes the assembly as a direct-fit replacement requiring no modification.

- The manufacturer describes PA66 plastic construction and intended use in crankcase ventilation.

## Pros

- One listed part number helps buyers compare the assembly with the part being replaced.
- Two ports and an NPT outlet connection are specified, which may help with a fitment check.

## Before you buy

- Fitment is claimed for 2023–2026 and 2011–2022 6.7L Powerstroke models, but the listing separately calls the older range “Old Models.” It also says 2011–2016 vehicles with sensors may require clearing the fault code after installation. Confirm compatibility and the sensor procedure for your exact truck. The listed 0.1 x 0.1 x 0.1-inch dimensions are unusual for an assembly, so verify them before using them for installation planning.

## In the box

- 1 air oil separator assembly (Included)

## A good fit for

- Owners checking a replacement crankcase ventilation air oil separator for a listed Ford F-250, F-350, F-450 or F-550 6.7L Powerstroke.
- Buyers who can compare the PC3Z-6A785-A reference and confirm year-specific fitment before purchase.

## Less suited to

- Buyers who need confirmed fitment without checking their truck’s year, engine and sensor configuration.
- Anyone relying on the listed dimensions as an installation measurement without confirming them.

## Customer feedback

There is only a single aggregate rating and no written customer feedback. That is too little evidence to establish reliability, fitment or installation experience. Buyers should base the decision on verified compatibility for their truck rather than the rating alone.
