URO 11157532649 Engine Crankcase Breather Hose - Vent Valve To Dip Stick Tube

BMW Crankcase Breather Hose

This URO engine crankcase breather hose restores the connection between the vent valve and dip stick tube on select BMW models. It is built with high-quality materials that resist cracking from engine heat and oil exposure, helping maintain proper crankcase ventilation and hydrocarbon control.

• Direct-fit replacement for the crankcase ventilation hose route from vent valve to dip stick tube
• High-quality materials resist splitting and cracking under heat and oil exposure
• Helps restore oil separator function for proper emission control
• Compatible with select BMW 323i, 325i, 330i, 525i, 530i, Z3, Z4, and X3 applications
• URO part number 11157532649 for OE-style replacement needs

Common Problems This Part Can Address

• Cracked or split breather hose between the vent valve and dip stick tube
• Oil vapor leaks in the crankcase ventilation circuit
• Reduced oil separator performance
• Emission control faults related to crankcase ventilation flow
• Vacuum leaks caused by deteriorated hose material

Installation Notes

Verify the vehicle’s production date and engine configuration before ordering, especially on 1998-1999 BMW Z3 and 528i applications with September 1998 build-date notes. Inspect the vent valve, dip stick tube connection points, and adjacent crankcase ventilation components for wear before installation. Confirm routing matches the original hose path on the vehicle.

Quality Assurance

URO backs this part with a 24-month unlimited mileage warranty. The hose is made from materials selected to handle continuous oil exposure and engine heat while supporting proper crankcase ventilation function.
