Product Description

The Arrowhead Oil Separator is an essential engine component designed for BMW petrol engines. Its primary function is to separate oil vapour from the crankcase gases, preventing oil from being drawn into the intake system and maintaining optimal engine performance. This oil separator is designed for specific BMW models and is a direct replacement for the original part.

This unit is compatible with selected BMW models using M42, M43, and M44 petrol engines, commonly found in E34, E36, E46, and Z3 (E36) series. Always confirm your exact model, year, engine size, and engine code before ordering to ensure correct fitment.

Common symptoms of a failing oil separator include increased oil consumption, blue smoke from the exhaust, rough idling, loss of engine power, oil leaks, poor fuel economy, and the presence of oil in intake hoses. If you notice any of these issues, the oil separator may need attention.

It is recommended to replace the oil separator if you observe the listed symptoms or during major engine servicing, especially on higher-mileage vehicles. Timely replacement helps prevent more serious engine damage and keeps your BMW running smoothly.
