The mechanicals are solid, but they run hot and the poor quality gaskets and less-than-tight mating surfaces hemorrhage oil eventually. Also, every BMW cooling system from say 2002 on is notorious. I know lots of mechanics who love the snap connectors, but the plastics bits couldn't suck more if they were engineered in a Play Doh lab. Then, the complex electronic systems engineered by Range Rover are asked to communicate with BMW sensors etc. it's just all bad. Another example is the budget front diff that was engineered for the truck. Early ones failed and were recalled and in my particular truck it appeared to be installed incorrectly and was pushing small amounts gear oil out the vent tube after long trips (the diff vent tube exits in the valley pan area) brilliant! The dealer replaced nearly every top end gasket and nobody could find the source of the oil in the valley pan. I (the furthest thing from a factory LR tech) found the vent tube problem within the first week of ownership. It was lucky I guess, but if I had TSBs and factory training, I'd have been looking at the timing covers as well.I know nothing about those trucks but thought the BMW engine were thought after. Is that an issue with their V8 model? (I think I heard someone complaining about the x5 engines).
