URO URO-000455 Oil Separator Hose Crankcase Breather PCV Replacement

The URO URO-000455 Oil Separator Hose is a quality replacement crankcase breather hose designed to restore proper positive crankcase ventilation (PCV) system function. This hose connects the engine's oil separator (air-oil separator) to the intake manifold, channeling blow-by gases and oil vapors away from the crankcase and back into the combustion process where they can be safely burned.

Over time, original rubber breather hoses become brittle and crack due to prolonged exposure to engine heat and oil vapor. A failed or cracked oil separator hose causes vacuum leaks that lead to rough idle, poor engine performance, lean fuel conditions, and increased hydrocarbon emissions. Replacing a worn hose promptly helps prevent oil from being drawn into the intake manifold and protects downstream engine components.

Key Features:

• Direct OE-style replacement for the original oil separator hose
• Manufactured to OE dimensions for correct fit and easy installation
• High-quality hose materials engineered to resist engine heat and oil vapor exposure
