Disadvantages of the Land Rover 46D engine
- In engines until 1999, sleeves often sank and the crankshaft jammed;
- Then the block was modernized and a small shoulder appeared to support the sleeves;
- In the same year, the unreliable GEMS injection system gave way to Bosch Motronic;
- Updated engines after 1999 often suffer from microcracks in the block walls;
- A lot of problems here are caused by capricious electrical sensors and a gasoline pump.
