2.25-LITRE DIESEL (1983 - 1984)
IT MAY be a throwback to the Series III and earlier, but this is the so-called 2.3 engine (actually still 2286cc), the stronger and allegedly smoother unit, thanks to having five main bearings instead of the early version’s three-bearing crankshaft.
This indirect injection engine featured pre-combustion chambers, one for every cylinder, fitted into recesses in the head, in which the fuel and air was mixed before reaching the real combustion chamber. This arrangement was the norm for the time and produced a relatively quiet combustion noise, though standing next to one of these engines on tickover might convince us otherwise.
Paradoxically, this was a highmaintenance engine that would withstand utter neglect. A cartridge oil filter, tappets to set and a timing chain that could stretch and put the fuelling out of kilter, all helped to make owner maintenance a rewarding art form – service it properly, and it would run forever – neglect it, and it would still run forever but with a lot of smoke and clatter. Performance was no better than the Series III version, though a solenoid fuel shut-off afforded the sophistication of the engine stopping when you turned the key off. The engine continued its previously successful run, also powering London taxis, and modified as a boat engine in the USA. • Maximum torque at 1500 rpm must make
this the coolest off-road crawler • Fixable almost anywhere by almost anyone,
but rarely needed fixing • Quite impervious to overheat, dodgy
mechanics, dodgy fuel and dodgy servicing • Almost impossible for it not to start
up instantly • Horrendously noisy on a
long journey • Masses of vibration • Road speeds more suitable for
