Disadvantages of the Land Rover 276DT engine
- The Siemens fuel system with piezo injectors delivers the most problems;
- Next, there is a rapid wear of the liners, up to the wedge and the breakdown of the crankshaft;
- Lubrication leaks are also regularly encountered here and the heat exchanger leaks especially often;
- The timing belt needs to be changed every 120 thousand km or if it breaks, the valves will bend;
- The weak points of the engine include the thermostat, EGR valve and the front crankshaft oil seal.
