- Description:
This is the genuine Ford crankcase ventilation oil separator, cataloged by Ford as Separator Assy - Oil. It is the sealed housing plumbed into the crankcase vent circuit that spins and coalesces oil mist out of blow-by gases before the vapors are routed back to the intake to be burned, returning the trapped oil to the crankcase. Verified fitment covers the 2008-2011 Ford Focus 2.0L Duratec HE, 2013-2018 Ford C-Max 2.0L hybrid, 2013-2020 Ford Fusion 2.0L hybrid, 2010-2013 Ford Transit Connect 2.0L, and 2013-2020 Lincoln MKZ 2.0L hybrid, along with related Police Responder and plug-in hybrid variants. Note this is an oil separator and crankcase vent valve, not a vapor canister purge valve, so buyers should verify function against the crankcase ventilation circuit rather than the evaporative-emissions purge system. A clogged, cracked, or diaphragm-torn separator causes oil consumption, oil in the intake tract, whistling or hissing vacuum noise, rough idle, a lit check-engine light, and in cold weather can allow crankcase pressure to push oil past seals. This OEM assembly matches the original Ford port layout and sealing surfaces so it bolts to the factory location and restores proper crankcase venting without leaks. Replace any O-rings or gaskets disturbed during removal, seat the separator squarely, and confirm the vent hoses are supple and correctly routed so the system pulls the designed vacuum.
