Product Description

The Arrowhead Oil Separator is an essential ENGINE OIL SEPARATOR designed for BMW models. This component is responsible for separating oil vapours from the crankcase ventilation system, helping to reduce oil consumption and maintain engine efficiency. Its robust plastic construction integrates seamlessly into your engine bay, ensuring reliable performance in demanding conditions.

This oil separator is compatible with a range of BMW vehicles, including models with engine codes N42 and N46, such as the E81, E87, E46, E90, E83, and E85. Always check your specific BMW’s model, year, engine size, and engine code before ordering to ensure proper 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 around the valve cover, and engine warning lights. You may also notice poor fuel economy or a strong oil smell from the engine bay.

If you experience any of these issues, it is important to inspect and replace the oil separator promptly. Over time, the separator can become clogged or cracked, reducing its effectiveness and potentially causing further engine problems.

Order your Arrowhead Oil Separator from MiMi Auto Parts for peace of mind and reliable nationwide delivery across South Africa. Our team is always available to assist you in confirming compatibility and ensuring you get the right part for your BMW.
