Land Rover engines can be considered fairly efficient engines in the 4×4 world. Since the 1990’s Land Rover engines have had decent performance and reliability when compared to how they used to fare. The engines in recent years have gone through a variety of redesigns due to buyouts, regulations and improvements, but the biggest change came with the Td5 moving away from purely mechanical engines (the 300Tdi had some electronic controls fitted on some models).
Most engines in Land Rovers are diesel, due to their better pulling power at lower RPM and better reliability in wading situations.
The best bet for an engine for an Expedition Land Rover is in the pre-Td5 era where worldwide parts and mechanics with the right skills are more easy to come by, not least for a simpler fault diagnosis. The 200Tdi holds a fuel consumption benefit over the 300Tdi and is simpler to service, but is a less refined engine.
