Its 2.5-litre inline-five diesel remained the sole powerplant for this variant until the Puma generation update in 2007.

Our Recommendation
Our Recommendation
If your ECU is intact, replacing the injector loom is a highly cost-effective preventative measure. However, if the head gasket has failed and the engine has overheated, a full rebuilt unit with upgraded steel dowels is the only reliable long-term solution to prevent recurrence.

Land Rover Defender 90 TD5 Engine ReplacementFrequently Asked Questions
Question 1How much does a Land Rover Defender 90 TD5 engine replacement cost-
A full rebuilt Land Rover Defender 90 TD5 engine typically costs between £3,500 and £5,500 for supply only. Reconditioned units start around £2,500, while used engines can be found from £800. Prices vary based on the specific engine code and whether you choose supply-only or a full supply and fit service.
- Rebuilt engines include upgraded steel dowels.
- Supply and fit adds approximately £650-£900 in labour.
- All rebuilt options include a 12-month warranty.
Question 2What are the signs of head gasket failure in a Land Rover Defender 90 TD5-
Early warning signs include white smoke from the exhaust, unexplained coolant loss, and oil that appears milky or frothy. In severe cases, the shearing of the plastic head dowels causes the cylinder head to lift, leading to a sudden loss of compression and engine misfires.
- Check coolant reservoir levels regularly.
- Inspect the oil filler cap for mayonnaise-like residue.
- Address overheating immediately to prevent block warping.
Question 3Is it worth replacing the engine in a Land Rover Defender 90 TD5-
Yes, given the current classic vehicle market. A well-maintained Land Rover Defender 90 TD5 holds a value of £8,000 to £18,000+. Investing £3,500-£5,500 in a rebuilt engine with a 12-month warranty is financially viable and protects the appreciating asset value of the vehicle, unlike a cheap used engine with no guarantee.
- Rebuilt engines resolve known TD5 design flaws.
- Warranty coverage provides long-term peace of mind.
- Preserves the vehicle's classic status and resale value.
Question 4What is the difference between the 10P and 15P Land Rover Defender 90 TD5 engines-
Both are 2.5-litre, 122hp inline-five diesel engines. The primary difference is that the later 15P (introduced in 2002) features upgraded steel head locating dowels to prevent the head gasket failures common in the earlier 10P. However, both codes remain susceptible to the injector loom oil leak issue.
- 10P: 1998-2002, requires steel dowel upgrade.
- 15P: 2002-2006, factory-fitted with steel dowels.
- Both require injector loom monitoring.
Question 5How long does a Land Rover Defender 90 TD5 engine replacement take-
A professional supply and fit service for a Land Rover Defender 90 TD5 typically takes 2 to 3 working days. This includes the removal of the old unit, thorough cleaning of the engine bay, installation of the replacement engine, and comprehensive testing to ensure all systems are functioning correctly.
- Nationwide delivery of the engine usually takes 1-2 days.
- Specialist workshops handle the full installation.
- Road testing and fluid checks are completed before handover.
