ArticleTimm's BMW (meeknet.co.uk)Difficulty: Hardwritten for E31 / E34 / E38 / E39

Timm's BMW M60, M62, M62TUB and N62TUB V8 Engines - PCV, PRV and OSV ↗

Explains how the V8 crankcase ventilation works: the cyclone oil separator sits behind bank 2's upper timing-chain cover and the pressure control valve on the back of the inlet manifold. Lists the symptoms (blue smoke, oil use, rough idle, lean codes) and why the PCV diaphragm is usually the first suspect before the separator.

Diagnosis/background article; separator replacement means removing the upper timing cover.
