Disadvantages of the Land Rover 46D engine
Up until 1999, sleeves frequently sank and the crankshaft jammed in engines; after that, the block was updated and a small shoulder appeared to support the sleeves; that same year, Bosch Motronic replaced the unreliable GEMS injection system; updated engines after 1999 frequently have microcracks in the block walls; many of these issues are caused by erratic electrical sensors and a gasoline pump.
