The cylinder head was redesigned mainly to reduce emissions and noise levels. The strong bottom end of the 2.25-litre engines, combined with a reputation for reliability, gave Land Rover the confidence to up the torque by increasing the stroke to produce a 2495cc capacity.

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. 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. Paradoxically, this was a high-maintenance engine that would withstand utter neglect. 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. 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. 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. Whichever one we think is best, the choice inevitably comes down to personal experience and preferences, and what you think a Defender should be. Maybe it’s the engine that lasts the longest, the most reliable, the cheapest to repair, the easiest to work on and how do fuel consumption and emissions figure in all this? Over the next few pages we’ll take a detailed look at these engines. The old 2.25-litre petrol engine is quieter and smoother than any of the diesels, it might not have sparkling performance, but do we need that in a utility wagon? And what does ‘best engine’ mean? There’s plenty of criteria to consider: power, torque, smoothness, quietness, best noise, best puller, most tuneable, best tow engine. These early machines started out with the 2.25-litre engines from the Series III which, could only be described as agricultural, with noise, vibration and aroma being their major characteristics, so we should delete those from the running right away.
Or are Tdi engines just noisy, slow, underpowered and outdated examples of exactly how bad an old diesel can be? I’m looking at 14 engines that have been fitted into the Defender range, and I’m including those fitted to the pre-Defender Ninety and One Ten models. On the other hand, surely the dependable old 300Tdi that can be fixed in the field and never breaks anyway, was the ultimate powerhouse. But is it a real Land Rover engine or is it a concocted answer to European emissions regulations with scant regard for the real needs of an off-road truck? Maybe this final TDCi is the most powerful, torquey and refined engine ever, even if it is a Ford unit. It should be a no-brainer that the latest and last 2.2-litre TDCi is the best-ever Defender engine.
