Description

Product Overview

FJ-OSA85C is a complete closed crankcase ventilation (CCV) oil separator assembly for the 6.7L Powerstroke diesel used in 2011-2016 Ford F-250 to F-550 Super Duty trucks. It is a direct replacement for Ford DC3Z-6A785-C and the Motorcraft FL-2172 assembly, and it also covers the earlier DC3Z-6A785-B, BC3Z-6A785-A/-B/-C/-EA and FC3Z-6A785-C numbers.

The assembly mounts at the original crankcase vent position and keeps the factory hose routing, so no adapter plate or extra bracket is needed. The housing is moulded in heat-resistant polymer with pre-installed O-rings, and a self-adhesive aluminium foil heat shield is supplied for the hose section beside the exhaust side of the engine.

Key Features

2011-2016 6.7L fitment — Fits Ford F-250, F-350, F-450 and F-550 Super Duty trucks with the 6.7L Powerstroke V8 diesel; the body bolts to the original CCV position with factory hose routing.
Replacement coverage — Cross-references DC3Z-6A785-C, DC3Z-6A785-B, DC3Z-6A785-A, BC3Z-6A785-A, BC3Z-6A785-B, BC3Z-6A785-C, BC3Z-6A785-EA, FC3Z-6A785-C and Motorcraft FL-2172.
Oil mist separation — Crankcase blow-by gas enters the separator, oil mist is collected on the internal media and the gas continues to the intake tract; collected oil drains back to the crankcase.
Crankcase vent sensor included — The assembly is supplied with the crankcase vent sensor fitted, as on the FL-2172 assembly, so the factory harness connects without adapters.
Sealing and heat shielding — Pre-installed O-rings seat against the crankcase vent port, and a self-adhesive aluminium foil shield is included for the hose run next to the exhaust side.
