URO 948-107-245-02 Crankcase Breather Hose Left to Right Valve Cover

The URO 948-107-245-02 is an engine crankcase breather hose designed to connect the left and right valve covers as part of your vehicle's Positive Crankcase Ventilation (PCV) system. This vent line plays a critical role in maintaining proper engine performance by allowing crankcase pressure to escape in a controlled manner.

Key Features:

• Direct replacement for OEM part number 948-107-245-02
• Connects left valve cover to right valve cover
• Essential component of the PCV system
• Helps prevent vacuum leaks and check engine lights
• Manufactured by URO Parts to meet or exceed OEM specifications

The PCV system vents positive crankcase pressure caused by combustion blow-by gases that leak past the piston rings. This breather hose routes these gases back into the intake air stream, reducing harmful emissions while maintaining proper engine ventilation. Damaged or deteriorated crankcase breather hoses are a common source of engine vacuum leaks and can trigger check engine lights in modern vehicles. Replacing a failed breather hose restores proper crankcase ventilation and helps maintain optimal engine performance.
