• Description:

  This is a genuine Ford crankcase ventilation tube, catalogued by Ford as Crankcase Tube and PCV Valve Hose under base number 6758, for the 3.5L EcoBoost twin-turbo V6. The tube routes crankcase blow-by vapors from the PCV system back into the intake tract so they can be reburned, maintaining proper crankcase pressure and emissions control on the turbocharged engine. It fits 2011-2014 Ford F-150 and 2011-2013 Lincoln Mark LT equipped with the 3.5L EcoBoost GTDI engine. A buyer typically searches for this part after finding a cracked, brittle, or collapsed ventilation tube, an oil-fouled or whistling hose, a rough idle or lean vacuum-related trouble codes, a hissing sound from the engine bay, or oil residue at the tube connections; the molded hose material hardens and splits with heat and age, causing unmetered air leaks and PCV faults. Ford lists this as a molded assembly designed to snap and seal to the crankcase and intake fittings without adapters. Inspect the mating grommets and quick-connect fittings when installing, seat both ends fully until they click, and confirm this suffix matches your build since routing changed across the 3.5L EcoBoost production run. Genuine Ford construction ensures the correct oil-resistant material and molded geometry so the tube seals properly and resists the underhood heat that destroys generic replacements.
