Land Rover 2.25-litre diesel engine

The Land Rover 2.25-litre diesel, engine code 10J, was the four-cylinder diesel that came with the Series IIA Land Rover, dated 1962 by Wikipedia and late 1961 by one owners page, and it replaced the original 2-litre diesel. It shared its block, valve gear, cooling and lubrication systems with the 2.25-litre petrol engine, with a forged crankshaft and different pistons, and like the petrol unit it is a dry-liner design built on the same production line. Its cylinder head used the same basic casting but was very different inside, being in essence an updated version of the head of the 2-litre diesel. It gave a modest rise in power and a useful jump in torque, but the main gain was that it was much quieter, more efficient and more reliable than the older unit. A five-bearing crankshaft was added in 1980. It powered the Series II, Series III and One Ten Land Rovers, the Austin FX4 London taxi as the FX4R from 1982 to 1985, where long idling shortened its life, and a marine version sold by Mercury.
