The Range Rover MKIII manufactured during the BMW-owned model years had the M62 specification engine. This engine is notorious for PCV (Positive Crankcase Ventilation) system failures. The PCV system regulates pressure inside the crankcase and when it fails, it can cause oil leaks, rough idle, and various fault codes.
