URO URO-008757 Crankcase Breather Hose PCV Vent Hose | OEM# 9146344

The URO Parts URO-008757 Crankcase Breather Hose (OEM# 9146344) is a direct-fit OE replacement crankcase ventilation hose engineered for Volvo vehicles. As a key component of the Positive Crankcase Ventilation (PCV) system, this hose routes blow-by gases — combustion gases that escape past the pistons — back into the intake air stream, reducing harmful hydrocarbon emissions and preventing damaging pressure buildup inside the engine.

A cracked or deteriorated crankcase breather hose is one of the most common causes of engine vacuum leaks, rough idle, oil consumption issues, and check engine lights. Replacing a failed hose with this quality URO Parts unit restores proper crankcase ventilation and emissions control.
