Product Description

The Arrowhead Hose Breather Oil Separator Valve Cover is designed for the breather engine system in select BMW models. This hose plays a key role in routing crankcase gases from the valve cover to the oil separator, helping to maintain proper engine ventilation and prevent oil vapour build-up. Its robust plastic construction and secure quick-connect fittings ensure a reliable seal and correct routing within the engine bay.

This breather hose is compatible with specific BMW models equipped with engines such as the N42 and N46, including popular models like the E87, E46, E90, X3 E83, and Z4 E85. Always confirm your vehicle’s model, year, engine size, and engine code before purchasing to ensure correct fitment.

Symptoms of a failing breather hose can include rough idling, increased oil consumption, visible oil leaks near the valve cover, engine warning lights, poor fuel economy, misfires, and a noticeable smell of oil vapour in the cabin. You may also experience reduced engine performance or hear hissing noises from the engine bay.

Replace this hose if you notice any signs of cracking, brittleness, or leaks, or if your BMW is showing the above symptoms. Timely replacement helps maintain optimal engine breathing and prevents further damage to the oil separator and related components.
