Keep crankcase vapors on the path the engine was designed for with the Standard Ignition V758 crankcase breather hose, which fits the 1997-2004 Jeep Grand Cherokee, 1997-2004 Jeep Wrangler and 1997-1998 Jeep Cherokee with the L6-4.0L engine.
This hose is part of the engine's crankcase ventilation system. It gives blow-by gases and vapors leaving the crankcase a route to follow, so the system can send them along their intended path instead of letting pressure build inside the engine. Heat and oil vapor can wear a breather hose over time. When the original is cracked, split or no longer seals at its connections, this hose replaces it.
Signs this part may need replacing: visible cracks or splits, a collapsed or loose section, or oil residue around the hose or its fittings. Other problems can cause similar symptoms, so inspect the crankcase ventilation system before replacing parts. For removal and installation, follow the vehicle service information.
See the Buyer's Guide tab for every listed vehicle.
