When your Discovery or Range Rover needs engine work, you will need to get it done correctly, or risk further trouble soon thereafter. As the author of this article found out to his cost and considerable inconvenience, taking the vehicle to your “friendly local mechanic” might just NOT be the right solution. (See the full article on the GCA website)
The main reason for going to a specialist is the need for specific knowledge of Land Rovers. True, they are merely variations of similar vehicles, but a Land Rover specialist will very likely have come across the problem before and will know what is required. He will also have the equipment and parts needed to do the job. Not knowing the specifics and/or ordering the wrong part will inevitably cause delays at best and potential future failures at worst when the replacement part does not quite fit or is damaged under load.
Certainly when it comes to appropriate equipment, the average mechanic is most unlikely to know that a full body lift is needed to perform any serious work on the engine of a late-model Disco or Range Rover

This is an extract from an article on the main GCA website – (accessible from a desktop, tablet and not from a mobile phone) The article is mainly directed at owners of Classic Range Rovers and Discovery 1 and 2 models.
The simplest “fix” for a 3.5 V8 is to change it to a 3.9 litre engine or even a reworked 4.6 engine. Vehicles already fitted with 3.9 engines can also be upgraded and/or have reworked 4.6 engines installed. Neither are cheap options, but the results are frequently outstanding. Additionally, the work is usually less expensive than replacing the vehicle, by the time all associated costs are taken into account – like insurance, financing etc. The outcomes are also predictable, whereas replacing one vehicle with another may not always be the better option.
Arguably, the best option is to change the power unit wither to a 4.0 litre or 4.6 litre engine taken from the P38 Range Rover. The major problem will be finding a suitable donor engine. If they were any good, they would probably not be available in the first place but regardless, complete reliability will only be achieved by a thorough rebuild that will include the fitting of “top hat” liners, cross-bolted mains, reworked heads, filters, gaskets, and so on
