Let’s talk money—replacing a Land Rover Defender engine isn’t cheap, but the costs depend on what you go for. A second-hand Land Rover Defender engine might tempt you with a low-price tag, sometimes as little as £1,000, but it’s a gamble. Hidden issues like faulty or defected engine parts could mean you’re shelling out for repairs before you know it. On the flip side, a reconditioned Land Rover Defender engine sits in the middle ground—think £2,000 to £4,000—where the major problems are sorted, making it a safer bet than used, but not quite as thorough as remanufactured.
