Land Rover Discovery 4 Engine Replacement & Supply in Ilford
If your Discovery 4 has suffered a serious engine fault, the first job is to identify the exact engine before deciding whether to repair, rebuild or replace it. Our Ilford workshop deals with Land Rover Discovery 4 engine enquiries across diesel and petrol variants, with reconditioned and replacement options, supply-only support and complete engine fitting.
Send the registration, mileage and symptoms and we will check the vehicle specification, narrow down the engine code and explain the available route. That matters on the Discovery 4 because the range includes several 2.7, 3.0 and 5.0-litre engines that are not interchangeable simply because the capacity looks similar.

Which engines are listed for the Land Rover Discovery 4?
The current website engine catalogue lists six Discovery 4 engine codes: 276DT, 306DT, 30DDTX, 306PS, 30HD0D and 508PN. These cover 2.7-litre and 3.0-litre diesel units, 3.0-litre petrol variants and a 5.0-litre V8. Because engine code, fuel type, output and ancillaries can differ, the vehicle registration should be checked before an engine is ordered or fitted.
Matched by registration and engine code
A “Discovery 4 3.0 engine” description is not enough to guarantee compatibility. Send the registration and any engine code you already have so the unit can be checked against the vehicle before quoting.
Replacement and reconditioned Discovery 4 engines matched to the vehicle
The Discovery 4 is now at an age where engine problems can range from repairable turbo, EGR, cooling or timing faults to serious internal damage. Some vehicles arrive after an oil-pressure warning or heavy knock; others have already been diagnosed with crankshaft, bearing, compression or overheating damage. The correct route depends on what has failed and whether the original engine remains suitable for rebuilding.
At our specialist Jaguar and Land Rover engine workshop in Ilford, we use the vehicle details and fault information to narrow down the engine specification first. We can then discuss a targeted repair, rebuild of the original engine, a reconditioned replacement engine or another replacement option, subject to availability and inspection.
For customers whose Discovery 4 is already with another garage, supply-only can be discussed. For owners who want one specialist workshop to manage the job, we can arrange engine supply and fitting from 36-A Fowler Road, Ilford IG6 3UT, with collection and delivery options available beyond the local area.
Land Rover Discovery 4 engine codes we can identify and quote
2.7 TDV6 Discovery 4 engine - 276DT
The 276DT is the 2.7-litre diesel V6 listed for the Discovery 4. When this engine develops a serious bottom-end knock, low oil pressure or crankshaft-related damage, continued driving can increase the repair scope very quickly. Timing-belt condition, turbocharger oil supply, EGR operation and the cause of any lubrication problem should also be considered before another engine is installed.
3.0 diesel Discovery 4 engines - 306DT and 30DDTX
The 3.0-litre diesel Discovery 4 needs careful diagnosis when there is heavy knocking, oil-pressure loss, metal contamination, smoke, poor boost or repeated engine warnings. Depending on the failure, work may involve the crankshaft and bearings, timing system, turbochargers, EGR or DPF-related systems, cooling components or a complete engine rebuild or replacement. The root cause should be identified before a replacement engine is returned to service.
3.0 petrol Discovery 4 engines - 306PS and 30HD0D
The 3.0-litre petrol variants listed in the catalogue require a different diagnostic route from the diesel engines. Misfires, coolant loss, overheating, compression problems, timing-related noise or supercharger-related drive concerns should be assessed before engine replacement is considered. A registration and engine-code check is essential because the petrol and diesel 3.0-litre units are completely different engine families.
5.0 V8 Discovery 4 engine - 508PN
The 508PN is the 5.0-litre V8 listed for the Discovery 4. On a V8 with major engine symptoms, the workshop assessment should consider cooling-system condition, oil leaks, timing-related noise, misfire, compression and evidence of overheating or lubrication problems. The aim is to establish whether the engine needs a targeted repair, cylinder-head or timing work, a rebuild or replacement.

Cannot see your Discovery 4 engine?
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.
Cannot see the exact engine you need?
Engine stock and exchange units can change. Send the registration, model year, engine code if known and a short fault description. We can check the appropriate Discovery 4 engine option before you commit.
Discovery 4 engine problems that need proper diagnosis
A warning light, smoke or loss of power does not automatically mean the engine needs replacing. The same symptom can come from a repairable turbo, EGR, DPF, cooling or fuel-system fault, or from serious internal engine damage. Diagnosis should come before an engine order.
Heavy knocking or bottom-end rumble
A deep metallic knock that follows engine speed can indicate bearing or crankshaft damage. On the 2.7 and 3.0 diesel engines, stop driving and have the oil pressure and internal condition assessed before further damage occurs.
Low oil pressure or oil warning
Low oil pressure can threaten crankshaft bearings, camshafts and turbocharger lubrication. The cause may be internal wear, oil-pump or pickup problems, contamination or another lubrication fault, so a replacement engine should not be fitted until the cause has been addressed.
Timing-belt or timing-system concerns
Diesel Discovery 4 engines have timing components that must be maintained correctly. Belt deterioration, tensioner problems or timing-related damage can create poor running or catastrophic internal contact. Petrol variants may present with different timing-related noise or faults and should be assessed separately.
Turbocharger, EGR or DPF symptoms
Smoke, poor boost, limp mode and repeated warning lights can originate from turbocharger, EGR or DPF-related faults rather than complete engine failure. These systems should be diagnosed because a failed supporting system can also contribute to engine damage.
Overheating or coolant loss
Repeated overheating can damage cylinder heads, head gaskets, bores and other internal components. Cooling-system leaks, poor circulation or other causes must be corrected before a repaired or replacement engine is put back into service.
Misfire, poor compression or rough running
On petrol variants, persistent misfire or low compression can point to ignition, valve, cylinder-head or deeper mechanical problems. Compression and leak-down testing can help separate repairable faults from major internal damage.
Engine seizure or metal in the oil
A seized engine, heavy internal noise or metallic contamination in the oil usually justifies a deeper inspection to determine whether the unit can be rebuilt economically or whether replacement is the better route.
Do not fit another engine until the original failure is understood
If oil starvation, overheating, turbocharger failure or another supporting fault caused the damage, fitting another engine without correcting the cause risks repeating the same failure.
What should you do when a Discovery 4 engine fails?
The best option is not decided by the warning light alone. It depends on the damaged components, condition of the block and crankshaft, cost of machining and parts, availability of a replacement engine, vehicle condition and how long you intend to keep the Discovery 4.
| 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, EGR, DPF, fuel, ignition or timing-related problem. |
| Rebuild your engine | The original engine is stripped, measured and rebuilt if its major castings and components remain suitable. | When internal damage is rebuildable and retaining the original unit is practical. |
| Reconditioned engine | A replacement engine that has been internally inspected and restored according to the condition found. | When the original engine is uneconomical to rebuild and you want more documented workshop work than a basic used unit. |
| Used replacement engine | An engine removed from another vehicle and supplied in used condition. | When a suitable unit is available and initial purchase cost is the main consideration. |
Not sure which route is best?
Send the registration, mileage and any diagnosis you already have. We can compare repair, rebuild and replacement routes against the actual Discovery 4 engine rather than guessing from symptoms.
Discovery 4 engine replacement, step by step
Send the registration and symptoms
Tell us the registration, mileage, warning lights, noises, smoke, overheating history and any diagnosis already completed.
Confirm the engine specification
We identify the relevant Discovery 4 engine code and check the vehicle details before discussing a replacement unit.
Assess the likely failure
Where the vehicle comes to our Ilford workshop, diagnostics and inspection help separate a repairable supporting fault from serious internal engine damage.
Agree the repair, rebuild or replacement route
We explain what is known, what further inspection may be required and which route is most appropriate before major work proceeds.
Choose supply only or supply and fit
If another garage is fitting the engine, we can discuss supply only. If you want one workshop responsible for the job, we can manage supply and fitting in Ilford.
Correct supporting faults and complete checks
Cooling, lubrication, turbo, fuel, EGR, DPF or other contributing faults should be corrected so the repaired or replacement engine is not exposed to the same cause of failure.
Discovery 4 engine supply and fitting from our Ilford workshop
If you are searching for a Land Rover Discovery 4 engine specialist near Ilford, our workshop is based at 36-A Fowler Road, Ilford IG6 3UT. We work specifically with Jaguar, Land Rover and Range Rover engines, allowing local customers in Ilford, East London and Essex to bring the vehicle to a specialist engine workshop rather than splitting the job between an engine seller and a general garage.
Supply only
If the Discovery 4 is already with your own garage, we can discuss an appropriate engine subject to confirmed specification and availability. Your installer should verify compatibility and correct any cause of the original failure before fitting.
Supply and fit
For owners who want one workshop to manage the engine replacement, we can arrange engine supply and fitting in Ilford. This keeps engine matching, removal, installation and post-fit checks under one job.
Local collection and UK delivery
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 subject to the job and engine.
How much does a Land Rover Discovery 4 engine replacement cost?
There is no single Discovery 4 engine price because the range includes different diesel and petrol engines, and the final cost depends on the exact code, failure, engine condition and whether you require supply only or complete fitting. A repairable turbo or cooling fault is a very different job from crankshaft damage, a seized engine or a complete replacement.
Warranty on Discovery 4 engine work
Warranty depends on the engine supplied and the work carried out. The website currently advertises reconditioned engine options with warranty cover of up to 6 months. The exact duration, parts and labour terms, fitting conditions and servicing requirements should be confirmed in writing with the quotation.
| Cost Factor | Why It Changes The Quote |
|---|---|
| Engine code | 276DT, 306DT, 30DDTX, 306PS, 30HD0D and 508PN are different units with different parts, availability and fitting requirements. |
| Failure type | Supporting-system repairs, timing work, crankshaft damage, overheating and complete seizure require very different labour and parts. |
| Original engine condition | A rebuild only makes sense when the main castings and components can be restored within acceptable tolerances. |
| Replacement type | Used, reconditioned and rebuilt engines have different preparation, history and warranty considerations. |
| Supply only or fitted | Vehicle recovery, removal, installation, fluids and associated workshop work affect the final figure. |
| Supporting faults | Cooling, turbo, DPF, EGR, fuel or lubrication faults may need correcting before the replacement engine is returned to service. |
For an accurate Discovery 4 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 a generic engine price.
Looking after a Discovery 4 after engine replacement or rebuild
A repaired, rebuilt or replacement engine should not be treated as the end of the diagnosis. Follow the written running-in or servicing instructions supplied with the job, monitor oil and coolant levels, investigate any warning light or leak immediately and make sure supporting systems remain healthy. On a reconditioned engine, the workshop should confirm any early oil-change or inspection requirements as part of the handover paperwork.
