• Description:

  This is a genuine Ford crankcase ventilation tube assembly for 20-23 Lincoln Aviator models. Ford catalogs this as a Tube Assembly; other common names for the same component are PCV Hose, PCV Valve Hose, EGR Tube, and Crankcase Breather Hose. The PCV tube vents blow-by gases out of the engine crankcase and routes them back into the intake so they are consumed during combustion. This is required for emissions compliance and also prevents crankcase pressure from blowing oil past the seals. On the Aviator the tube routes around the cam cover, over the engine, and into the intake tract; the path puts the molded plastic and rubber in regular contact with engine heat and oil mist. Failure symptoms include a check engine light with lean or EVAP codes, a whistling sound under load, increased oil consumption, oil residue around the tube ends, audible cracking at the quick connects, and rough idle when the line is unseated. This is the original equipment Ford part with the correct connector profiles, routing curvature, and internal restriction for the 3.0L twin-turbo V6 used in the Aviator. The catalog name is Tube Assy. Inspect the tube for cracks at the connector ferrules, replace any single-use O-rings or retainer clips with new parts, and verify the line routes clear of hot exhaust components before reconnecting the battery.
