Looking for the correct Land Rover Discovery 3 engine after a breakdown or major engine fault? Our Ilford workshop supplies and fits Discovery 3 engine options, including reconditioned, replacement and rebuild routes, with the engine matched to your vehicle before you commit.
The Discovery 3 was sold with more than one engine. Send your registration, mileage and fault details first so we can confirm the relevant engine code, discuss whether the original unit is repairable and provide a written quotation for the right route.
The current engine catalogue for the Land Rover Discovery 3 lists three engine codes for 2004-2009 vehicles: the 2.7-litre TDV6 diesel 276DT, the 4.0-litre V6 petrol 406PN and the 4.4-litre V8 petrol 448PN. The correct replacement must be matched to the individual vehicle rather than chosen by engine size alone.
The Discovery 3, also known by the L319 chassis designation, is a capable four-wheel-drive vehicle, but by now many examples have covered substantial mileage. When the engine develops a serious fault, the important question is not simply “where can I buy another engine?” It is whether the original engine can be repaired, whether a rebuild makes sense, and which replacement unit is actually compatible with the vehicle.
At our specialist Jaguar and Land Rover engine workshop in Ilford, we start with the registration, engine specification and fault. That avoids a common problem with older Land Rovers: ordering a unit that appears similar but differs in engine code, ancillaries, electronics or configuration.
We can discuss supply-only engines for vehicles already at another garage, or manage the job as a complete Discovery 3 engine supply-and-fit service from our workshop at 36-A Fowler Road, Ilford IG6 3UT.
A “Discovery 3 2.7 diesel” description is useful, but it is not the whole compatibility check. Send the registration and any engine code or diagnostic report you already have before ordering.
Search the Discovery 3 engines currently listed, or send your registration if the exact engine is not shown. Availability changes, so a registration check is the fastest way to get a confirmed answer.
| Model | Engine Code | Engine Size | Power | Year Range | Action |

The online list is not the final answer. Send your registration and the current engine fault, and we can check the correct engine specification and availability.
The 276DT is the 2.7-litre turbo-diesel V6 commonly associated with the Discovery 3. It combines strong low-speed torque with the refinement expected from the L319, but it also deserves careful diagnosis when there is bottom-end noise, loss of oil pressure, heavy smoke, turbo trouble or a sudden no-start condition.
The 406PN is the 4.0-litre naturally aspirated petrol V6 listed for the Discovery 3. Petrol-engine enquiries often arrive with different symptoms from the TDV6, including misfires, rough running, overheating, oil leaks or loss of compression. A proper test avoids replacing an engine when the fault is confined to ignition, cooling or another repairable system.
The 448PN is the 4.4-litre naturally aspirated V8 listed in the Discovery 3 catalogue. On an older V8, cooling-system health, oil leaks, valve-train or timing-related noise, smoke and compression should all be checked before a replacement decision. If internal damage is confirmed, we can discuss rebuild or engine replacement options based on the condition found.
Engine availability can change. Send the vehicle registration, model year, mileage and current fault so we can check the correct engine specification and the options available.
A warning light or smoke does not automatically mean the Discovery 3 needs a replacement engine. The same symptom can come from a repairable component or from serious internal damage. Diagnosis should separate those two situations before money is spent on another engine.
A deep metallic knock that follows engine speed can indicate bottom-end wear, bearing damage or a crankshaft problem. On a 276DT, stop driving and have the engine assessed before the damage becomes more extensive.
An oil-pressure warning can indicate lubrication failure, internal wear or another fault that threatens bearings and turbocharger lubrication. Continued driving can turn a repairable fault into a complete engine failure.
The 2.7 TDV6 uses a timing-belt system that must be maintained correctly. Timing noise, poor running, belt-related damage or a failed tensioner needs prompt investigation because valve and piston damage can follow a timing failure.
Blue or grey smoke, excessive oil use, whistling or a sudden drop in boost can indicate turbocharger trouble. The engine and intake system should be checked for oil contamination before a replacement unit is fitted.
Loss of power, rough running and fault codes can come from EGR or airflow problems rather than complete engine failure. These faults are particularly relevant on diesel vehicles and should be diagnosed first.
Cooling-system faults can distort cylinder heads, damage head gaskets and create more serious internal engine damage. The root cause of overheating must be corrected before any replacement engine is returned to service.
On 4.0 V6 and 4.4 V8 petrol variants, persistent misfires, rough running or low compression can point to ignition, valve, cylinder-head or deeper mechanical problems. Compression and leak-down testing help define the real scope.
A seized engine, heavy internal noise or visible metal contamination normally justifies a deeper strip-down assessment to decide whether rebuilding is practical or replacement is the better route.
If oil starvation, cooling-system failure, turbo damage, fuel contamination or another root cause is left unresolved, the replacement engine can be exposed to the same problem.
The right answer depends on what has actually failed inside the engine, the condition of the vehicle and the cost difference between repair, rebuild and replacement. We prefer to explain the options rather than assume every breakdown requires a complete engine.
| Option | What It Means | When It May Suit |
|---|---|---|
| Targeted repair | Only the failed system or component is repaired when the main engine remains serviceable. | When diagnosis finds a repairable turbo, cooling, fuel, EGR, ignition or timing-related fault without major internal damage. |
| Rebuild your engine | The original engine is stripped, measured and rebuilt if its main castings and components remain suitable. | When you want to retain the original unit and the internal damage is rebuildable. |
| Reconditioned engine | A replacement unit that has been internally inspected and restored according to the condition found. | When the original unit is uneconomical to rebuild and you want more workshop history than a typical used engine. |
| Used engine | A second-hand engine supplied in its existing used condition. | When initial cost is the main priority and a suitable verified engine is available. |
Send us the registration, mileage and diagnosis. We can compare repair, rebuild and replacement against the actual Discovery 3 rather than giving a generic recommendation.
Tell us the vehicle registration, mileage, warning messages, noises, smoke or existing garage diagnosis. Include the engine code if you already know it.
We identify whether the Discovery 3 uses the 276DT, 406PN, 448PN or another verified configuration before discussing availability or cost.
Where the vehicle comes to our Ilford workshop, diagnostic checks can include compression, oil pressure, leak-down testing and inspection for metal or coolant contamination as appropriate.
We explain what has failed and whether a focused repair, rebuild, reconditioned engine or replacement unit is the sensible option.
If another garage is carrying out the work, ask about supply. If you want one workshop to handle the engine and installation, choose supply and fit in Ilford.
Any cause that could damage the replacement engine - such as cooling, lubrication, turbocharger or fuel-system trouble - should be addressed before final testing and handover.
If you are searching for a Land Rover Discovery 3 engine specialist near Ilford, our workshop is based at 36-A Fowler Road, Ilford IG6 3UT. We handle Jaguar, Land Rover and Range Rover engine work, so the engine, diagnosis and fitting can be managed as one job where appropriate.
If the vehicle is already with your own garage, we can discuss a suitable Discovery 3 engine subject to confirmed specification and availability. Your installer should verify all fitment and supporting-system requirements before installation.
For owners who want one workshop responsible for the engine replacement, we can arrange supply and fitting in Ilford. This keeps engine matching, removal, installation and post-fit checks under one specialist workshop process.
We serve Ilford and surrounding East London and Essex areas directly. Collection and delivery can also be discussed for customers further away, with mainland UK engine supply available depending on the job.
There is no meaningful single price for every Discovery 3 engine. A 2.7 TDV6 replacement, a 4.0 V6 petrol engine and a 4.4 V8 engine have different availability, parts, labour and failure patterns. The final quote also depends on whether the engine can be repaired, whether a rebuild is viable and whether you require supply only or complete fitting.
Warranty depends on the engine supplied and the work carried out. The website currently advertises reconditioned engine options with warranty cover of up to 12 months. The exact duration, parts and labour position, servicing requirements and exclusions should be confirmed in the written quotation before installation.
| Cost Factor | Why It Changes The Quote |
|---|---|
| Engine code | 276DT, 406PN and 448PN are different engines with different parts and availability. |
| Failure type | A turbo, cooling or timing repair can be very different from crankshaft, bore or seizure damage. |
| Original engine condition | A rebuild is only sensible if the major castings and components remain within repairable limits. |
| Used vs reconditioned | Condition, preparation and warranty differ between used and reconditioned replacement units. |
| Supply only vs fitted | Removal, installation, fluids, filters, diagnostics and related repairs affect the final fitted price. |
| Supporting faults | Cooling, oil-pressure, turbo, fuel or electrical faults may need correction to protect the replacement engine. |
For an accurate Discovery 3 engine price, send the registration, engine code if known, mileage, postcode and a short description of the fault. We can then quote against the actual vehicle rather than publish a generic number that may not apply.
A Discovery 3 engine replacement is a major job, and many owners come to us after a breakdown, a low-oil-pressure warning, a severe knock or an existing diagnosis from another garage. Our role is to narrow the problem down, identify the correct engine and explain the available route clearly before you spend money on a replacement.
Send your registration and a short description of the engine problem. If you know whether the vehicle has a 276DT, 406PN or 448PN engine, include the code. We will use the details to help identify the correct engine and discuss the available repair, rebuild, reconditioned or replacement routes.
| What To Send | Why We Need It |
|---|---|
| Vehicle registration | To identify the Discovery 3 and narrow down the engine specification. |
| Mileage | Helps put the failure and repair decision into context. |

Yes. Supply-and-fit support is available through our workshop at 36-A Fowler Road, Ilford IG6 3UT. Supply-only can also be discussed when another garage will complete the installation.
The 276DT can present with crankshaft or bearing-related failure, low oil pressure, turbocharger problems, timing-belt issues, EGR faults, smoke and overheating. The exact cause should be diagnosed before deciding the engine needs replacement.
276DT is the 2.7-litre turbo-diesel V6 engine code listed for the Discovery 3. The live catalogue shows 2720cc and 140 kW / 190 hp for 2004-2009 vehicles.
Possibly. If the block, crankcase and other major components remain suitable, rebuilding the original engine may be practical. A strip-down and measurement are needed before that decision can be made confidently.
A reconditioned engine has been internally inspected and restored according to the condition found, while a used engine is normally supplied with its existing wear and history. Compare condition, warranty, total fitted cost and how long you plan to keep the vehicle.
Price depends on the engine code, failure, condition, availability and whether you need supply only or complete fitting. Send the registration and diagnosis for a vehicle-specific written quote.
Warranty depends on the engine and work supplied. The website advertises reconditioned engine options with cover of up to 12 months, with exact terms confirmed on the quotation.
Collection and delivery options are available across mainland UK. Send your postcode with the enquiry so the most suitable arrangement can be discussed.
A persistent metallic knock can indicate serious bottom-end damage. Continuing to drive may make the failure worse, so stop when safe and arrange diagnosis or recovery.
If you do not know the code, start with the registration and vehicle details. If you already have an engine code from the vehicle, VIN data or a diagnostic report, include it with the enquiry.
