Product Description

This Arrowhead engine oil separator is designed for select BMW petrol models, serving a crucial role in managing crankcase ventilation. The oil separator helps separate oil vapour from the blow-by gases before they are recirculated into the intake, reducing oil consumption and preventing contaminants from entering the engine. Over time, the separator can become clogged or fail, leading to a range of engine performance issues.

This part is compatible with BMW models such as the E36, E39, E38, and Z3 fitted with M50, M52, or S52 petrol engines. However, always confirm your vehicle’s model, year, engine size, and engine code before ordering to ensure correct fitment.

Common symptoms of a failing oil separator include increased oil consumption, visible smoke from the exhaust, rough idling, loss of power, oil leaks, and engine warning lights. You may also experience poor fuel economy and a noticeable drop in engine performance.

When replacing the oil separator, it is important to inspect all related hoses and seals for signs of wear or blockage. Timely replacement helps maintain efficient engine operation and prevents costly damage caused by oil contamination or excessive crankcase pressure.
