Motorcraft PCV Valve Crankcase Ventilation Hose

The Motorcraft PCV valve crankcase ventilation hose is a replacement breather hose for the positive crankcase ventilation (PCV) system. Motorcraft is Ford's genuine parts brand, and this hose is engineered to carry crankcase vapors and blow-by gases from the engine back to the intake so they can be burned. This helps control emissions and keeps crankcase pressure in balance.

Key Features:

• Carries blow-by vapors between the crankcase, PCV valve, and intake system
• Made for the heat, oil vapor, and fuel vapor found in the engine compartment
• Helps reduce crankcase pressure, sludge buildup, and oil leaks
• Supports proper emissions system operation
• Direct-fit replacement designed to match original equipment form and function

A cracked, brittle, or collapsed PCV hose can cause rough idle, vacuum leaks, oil consumption, and a check engine light. Replacing it restores proper crankcase ventilation and helps protect engine seals and gaskets. This product line is also known as a PCV hose, crankcase breather hose, or crankcase vent hose. Each part number in the line has its own specifications.
