Discovery 3 Engine Replacement Cost: A UK Price Guide
Discovery 3 engine replacement cost depends mainly on the engine and the labour. Unit-only 2.7 TDV6 engines are advertised from about £2,400–£3,200, and fitted packages run to around £5,800, because the engine usually comes out with the body lifted off the chassis. This guide compares advertised prices and lists what a full quote should cover. It also helps you decide whether replacement is worth it on an older Discovery.
The Discovery 3 is now old enough that an engine failure forces a hard decision. Do you replace the engine, rebuild it, or sell the car?
Here is what independent suppliers currently advertise:
- 2.7 TDV6 diesel, unit only: from about £2,400–£3,200. Fitting and possibly VAT are extra.
- 2.7 TDV6, fitted package: around £5,800, including VAT and labour.
- 4.4 V8 petrol, fitted package: around £6,500.
Labour is unusually heavy on this model. On the Discovery 3, the engine is usually removed by separating the body from the chassis.
Discovery 3 Engines and Why Replacement Is Costly
Engines Fitted and the Body-Off Factor
Engine | Code | Fuel | Notes |
| 2.7 TDV6 | 276DT | Diesel | Most UK Discovery 3s; replacement units are the easiest to find |
| 4.4 V8 | 448PN | Petrol | Less common in the UK; units are dearer |
| 4.0 V6 | 406PN | Petrol | Rare in the UK |
The engine codes above are as listed on the Vogue Technics Engine Rebuild Discovery 3 page.
The Discovery 3 uses a combined body-and-chassis design. Because of this, major engine work is commonly done with the body lifted off the chassis. Owners describe body-off engine replacements on Discovery 3 forums (Disco3.co.uk).
The body-off approach takes more labour, but it gives good access. While the body is off, it can be worth renewing parts that are hard to reach otherwise:
- turbo oil feeds;
- glow plugs;
- coolant pipes;
- engine mounts.

These figures suggest that body-off labour, fluids and extras roughly double the price of a unit-only 2.7 TDV6.

Is It Worth Replacing a Discovery 3 Engine?
Replace, Rebuild or Walk Away
Situation | Likely route |
| Crankshaft or bearing failure, block salvageable | Engine rebuild, keeping the engine's known history |
| Seized, holed block, or rebuild uneconomical | Reconditioned or used replacement |
| Body, chassis, gearbox or air suspension also poor | Compare the total cost against the car's value; replacement may not make sense |
| Engine faults without internal damage | Targeted engine repair |
The 2.7 TDV6's best-known serious fault is crankshaft and bearing failure. For symptoms and causes, see our guide to Discovery 3 engine problems and repair costs.
Before committing, weigh the full fitted quote against three things:
- the car's market value with a sound engine;
- any other work it needs;
- how long you plan to keep it.
Frequently Asked Questions
Discovery 3 Engine Replacement Cost FAQs
How much does a Discovery 3 engine replacement cost?
Unit-only 2.7 TDV6 engines are advertised from about £2,400–£3,200. Fitted packages are estimated at around £5,800 for the TDV6 and £6,500 for the 4.4 V8, including VAT and labour.
Why is Discovery 3 engine replacement so expensive?
Mainly because of labour. The engine is usually removed with the body lifted off the chassis.
Is it worth replacing the engine in a Discovery 3?
It can be, if the car is otherwise sound and you plan to keep it. If the body, chassis or gearbox also need work, compare the total cost with the car's value first.
Is a rebuild cheaper than a replacement?
Sometimes. If the block and crankshaft can be saved, a rebuild avoids sourcing a unit of unknown history. The final cost depends on what the strip-down finds.
Can a Discovery 4 engine go into a Discovery 3?
The Discovery 4 mostly used the 3.0 TDV6/SDV6, which is a different engine from the Discovery 3's 2.7. Fitting one is a conversion rather than a straight swap, and it involves wiring, ECU and ancillary changes.
