Keep your engine's crankcase ventilation path clear with the Standard Ignition Engine Crankcase Breather Hose V758. It installs as a direct-fit replacement for the listed applications: the 1997-1998 Jeep Cherokee, the 1997-2004 Jeep Grand Cherokee, and the 1997-2004 Jeep Wrangler.
A crankcase breather hose carries blow-by gases and oil vapor along the intended ventilation route between the crankcase and the engine's ventilation system, helping the crankcase breathe as designed. Over time these hoses can harden, crack, split, or collapse, which can disrupt normal crankcase ventilation and let oil mist or vapor escape at the connection.
- Mechanical job: routes crankcase blow-by gases and oil vapor along the factory ventilation path.
- Direct-fit: replaces the breather hose on the listed Jeep applications.
- Signs it may need replacing: a hardened, cracked, split, or collapsed hose, or oily residue around the hose ends.
If a deteriorated breather hose is the cause of your ventilation issue, this replaces it. We recommend diagnosing the underlying cause before replacing.
Interchange: Manufacturer part number V758.
