Keep crankcase blow-by moving along its intended path with the Standard Ignition Engine Crankcase Breather Hose V773. It drops in as a direct-fit replacement for the 2005-2010 Ford Explorer, 2007-2010 Ford Explorer Sport Trac, and 2005-2010 Mercury Mountaineer, giving blow-by gases a clean, sealed route through the engine's ventilation system.
A crankcase breather hose carries blow-by vapors along the intended route so pressure doesn't build inside the engine. Over time the original hose can crack, harden, or collapse, letting vapors and oil mist escape and upsetting the ventilation flow.
- Direct-fit routing: designed to follow the original hose path and connect at the factory points on the listed applications.
- Ventilation function: channels crankcase blow-by gases through the intended path, helping limit oil-mist escape and pressure buildup.
- Replacement part: if a cracked, collapsed, or leaking breather hose is the cause of oil residue or a ventilation complaint, this replaces the worn original.

What does a crankcase breather hose do?
It routes crankcase blow-by gases through the engine's intended ventilation path, helping limit oil-mist escape and prevent pressure from building inside the crankcase.
What are signs my breather hose may need replacing?
A cracked, hardened, or collapsed hose can leak vapors and oil mist and disrupt ventilation flow. Diagnose the cause before replacing, since other components can produce similar symptoms.
What interchange numbers does this hose cross to?
It replaces PCV858, 2-9844 (29844), 5L2Z9E498AA, 5L2Z9E498BA, and 6L2Z9E498A. The manufacturer part number is V773.
Is this the same as a PCV valve?
No. This is the crankcase breather hose that carries ventilation gases; it is a separate piece from the PCV valve, though both are part of the crankcase ventilation system.
