Helpful product answers
What is the purpose of the Oil Separator for BMW M50, M52, and S52 engines?
The Oil Separator helps to separate oil vapors from the crankcase gases before they are recirculated into the intake system. This prevents oil contamination in the intake manifold and reduces emissions. It is essential for maintaining engine efficiency and longevity in BMW 3 Series E36, 5 Series E39, 7 Series E38, and Z3 models with these engines.

Common signs include increased oil consumption, smoke from the exhaust, or a rough idle. A clogged or faulty separator can cause pressure build-up in the crankcase, leading to leaks or engine performance issues. Regular inspection during servicing is recommended to avoid damage.
Can I install the Oil Separator myself on my BMW 3 Series E36?
While it is possible for experienced DIYers, installation requires careful handling to avoid damaging hoses or seals. Incorrect installation can cause vacuum leaks or oil leaks. If unsure, consult a professional or a Trade Partner for proper fitting to ensure optimal performance.
