Product Description

This Arrowhead hose breather oil separator is an essential engine breather component for selected BMW models. Designed to manage crankcase ventilation, it helps separate oil vapours from air before returning clean air to the intake, supporting efficient engine operation and emissions control. The unit features a flexible hose with moulded bends and secure plastic fittings, ensuring a snug fit and reliable sealing within the engine bay. An integrated electrical connector is present, which may interface with engine management systems for accurate monitoring.

Compatibility for this breather engine hose is specific to certain BMW models, including popular series like the E87, E90, E60, and Z4 E85 with the N52 engine. Always confirm your vehicle's model, year, engine size, and engine code before ordering to ensure correct fitment.

Common symptoms of a faulty breather hose or oil separator include rough idling, increased oil consumption, visible oil leaks, check engine light activation, whistling or hissing noises from the engine, poor fuel economy, and excessive exhaust smoke. These issues can indicate that the breather hose is cracked, blocked, or leaking, affecting the engine's ventilation system.

Replace the breather oil separator hose if you notice any of these symptoms, or as part of routine maintenance when working on the crankcase ventilation system. Timely replacement helps prevent oil leaks, engine contamination, and potential damage to other components.
