Product Description

Ensure your BMW’s engine breathes properly with this Arrowhead hose breather oil separator valve cover, designed for models requiring precise crankcase ventilation. This breather hose forms a vital link between the valve cover and the oil separator, helping to direct blow-by gases away from the engine and reduce oil vapour build-up. With its robust rubber construction and integrated electrical connector, it is engineered to fit select BMW engines, supporting both performance and emissions control.

This part is compatible with various BMW models, including certain E87, E90, E60, and Z4 (E85) vehicles with N52 engines. Always confirm your BMW’s model, year, engine size, and engine code to ensure correct fitment before ordering.

A faulty breather hose or oil separator connection can cause rough idling, increased oil consumption, oil leaks around the valve cover, poor engine performance, whistling noises, or even trigger the check engine light. You may also notice excessive smoke from the exhaust or a strong smell of oil vapour.

Replace the breather hose if you spot cracks, oil seepage, or signs of deterioration, or if you experience any of the above symptoms. Regular inspection is recommended, especially on higher-mileage BMWs, to avoid related engine issues.
