  Vent Hose, Tube Assembly

• Description:

  This genuine Ford crankcase ventilation tube is the positive crankcase ventilation hose assembly for 2020 through 2026 Ford Transit vans with the 3.5L V6, cataloged by Ford as Tube Assembly, Crankcase Emission Control, and also listed as the PCV valve hose. It routes blow-by vapors out of the crankcase and back into the intake tract so they are burned rather than vented, maintaining correct crankcase pressure and helping control emissions and oil consumption. Drivers replace this tube when it becomes cracked, hardened, collapsed, or disconnected, which can trigger a check-engine light, rough idle, whistling or vacuum-leak noise, oil leaks from seals pushed by crankcase pressure, or a failed emissions test. The molded routing and fittings are shaped to the Transit engine bay so the hose seats without kinking and holds a proper seal at each connection. This is a direct-fit replacement matched to the factory quick-connect ports. Inspect the mating fittings and grommets for cracks or oil swelling and replace them if needed, and seat each connector fully until it clicks. Confirm the 3.5L engine application before ordering, as crankcase vent routing differs by engine displacement across the Transit and related lineups.
