Hi, I'm not a mechanic, and I've only owned a disco 4 for 12 months. Bought it from a dealer who abought from Highway patrol with 200000 miles on the clock. The problems I’ve just read above happened to my car. Evidently the oil pump failed and if it wasn’t for needing new cam belts I wouldn’t have realised the internal damage to the engine. After spending £5000 to replace belts and repair everything it’s still blowing white/grey smoke under heavy acceleration and there is a rough/rattle at start-up. Not sure what I should do next apart from sell it! Any thoughts gratefully received.
