Apex Engines supplies and fits quality Land Rover Discovery engines for customers across the UK. We provide used and reconditioned engines for Land Rover Discovery models, including Discovery 3, Discovery 4 and Discovery Sport. Our team can help when your engine has failed, developed a serious fault or needs a complete rebuild.
A Land Rover Discovery engine replacement can often cost less than buying another vehicle. We offer practical options for different budgets. You can choose a tested used engine or a fully reconditioned engine. Our technicians inspect each engine before fitting. We also provide engine diagnostics, engine repair, engine rebuilding, engine fitting, vehicle recovery and delivery services.
Our in house rebuilding facility allows us to inspect, clean, machine and rebuild engines under one roof. We check the engine specification, engine code and vehicle details before recommending a suitable unit. This helps prevent compatibility problems and unnecessary costs. Whether you own a diesel or petrol Land Rover Discovery, we can assess the fault and explain the best solution. We aim to make the process clear, reliable and simple. Every job starts with proper checks and a clear quote.

Soot build-up from diesel use and short journeys |
We test the EGR system and repair the engine fault or supply a replacement unit |
DPF blockage |
DPF warning light, reduced power, frequent regeneration |
Soot build-up and repeated short trips |
We diagnose the DPF and check whether the engine has suffered damage |
Overheating and cylinder head damage |
Coolant loss, white smoke, high temperature, oil and coolant mixing |
Cooling system failure or continued overheating |
We pressure test the system and inspect the cylinder head and head gasket |
Injector failure |
Rough idle, misfire, smoke, hard starting |
Worn injector, poor spray pattern or injector seal failure |
We test the fuel system and inspect the engine for piston or cylinder damage |
Oil leaks and oil consumption |
Low oil level, blue smoke, oil warning light |
Worn seals, piston rings, turbo or internal engine wear |
We test oil pressure, compression and the engine internals before repair or replacement |
Used Land Rover Discovery Engines
A used Land Rover Discovery engine can be a suitable choice when you need a lower-cost replacement. Used engines are removed from donor vehicles and checked before sale. We inspect compression, oil pressure, leaks and general condition.
We can supply used engines for several Discovery models and engine sizes, subject to availability. The correct engine depends on the vehicle year, fuel type, engine code, gearbox and specification. We check these details before confirming a replacement.
A used engine is often suitable for an older Discovery that has a good gearbox, chassis and body. It can restore the vehicle without the cost of a new engine. Our team can supply the engine for delivery or arrange a complete supply and fit service at our workshop.
Reconditioned Land Rover Discovery Engines
A reconditioned Land Rover Discovery engine is rebuilt after detailed inspection. The engine is stripped, cleaned and measured. Damaged and worn components are repaired or replaced. The engine is then rebuilt and tested before fitting.
Our in house rebuilding facility allows us to manage the main stages of the work ourselves. This includes inspection of the crankshaft, cylinder head, pistons, bearings, timing parts, oil system and cooling system. The exact work depends on the engine fault and the condition of each component.
A reconditioned engine costs more than a standard used engine, but it offers a stronger long-term solution. It is often the better choice for a Discovery with high mileage, major internal damage or repeated engine problems.
Land Rover Discovery 3 Engine Replacement
The Land Rover Discovery 3 is commonly fitted with the 2.7 TDV6 diesel engine. Some vehicles may require different specifications or petrol engine options. We supply used and reconditioned Discovery 3 engines, subject to stock and compatibility checks.
Common Discovery 3 engine faults include crankshaft and bearing damage, oil leaks, overheating, turbo problems and loss of power. Continuing to drive after a knocking noise or oil pressure warning can cause more damage.
We begin with engine diagnostics and a condition check. If the original engine can be repaired, we explain the rebuild option. If the damage is too severe, we can supply and fit a tested used or reconditioned replacement engine.
Land Rover Discovery 4 Engine Replacement
The Land Rover Discovery 4 is commonly associated with 3.0 TDV6 and SDV6 diesel engines. These engines provide strong torque for towing and off-road driving, but serious faults can occur if early warning signs are ignored.
Crankshaft failure, bearing wear, timing system faults, turbocharger problems, injector faults and overheating can lead to complete engine failure. Symptoms may include heavy knocking, low oil pressure, smoke, poor acceleration and engine warning messages.
Apex Engines supplies used and reconditioned Discovery 4 engines. We check the engine type and code before offering a quote. Our supply and fit service includes removal of the failed unit, fitting of the replacement and final testing.
Land Rover Discovery Sport Engines for Sale
We supply used and reconditioned Land Rover Discovery Sport engines. This includes suitable petrol and diesel options, subject to model, year and availability.
Discovery Sport diesel engines may develop DPF blockage, EGR carbon build-up, turbo faults and oil-related problems. Petrol engines may suffer from timing system faults, overheating and internal wear. The same warning sign can have different causes, so accurate diagnostics are important.
If the engine has low compression, serious timing damage, heavy smoke or major internal wear, replacement may be more cost-effective than repair. We compare the available options and recommend a suitable engine for your vehicle.
Discovery Engine Diagnostics, Repair and Rebuilding
Engine diagnostics help identify the real cause of a fault. Warning lights do not always mean that the complete engine needs replacing. The problem may be linked to the fuel system, turbocharger, cooling system, timing system or emissions parts.
We inspect the vehicle and use diagnostic checks to assess the fault. Where possible, we repair the original engine. For serious damage, we can rebuild the engine or supply a replacement unit.
Engine rebuilding may include inspection of the crankshaft, bearings, pistons, cylinder head, oil pump, timing parts and seals. The work depends on the damage found after strip-down. We explain the required work before starting the rebuild.
Fast Engine Supply and Fit Service
Our Land Rover Discovery supply and fit service covers the full replacement process. We source a suitable used or reconditioned engine, remove the failed unit and fit the replacement at our workshop.
Before fitting, we confirm the engine code and vehicle details. We also check related components that may have caused or suffered from the original failure. After installation, we complete diagnostic checks and test the vehicle before handover.
We also offer vehicle recovery and engine delivery across the UK. If your Discovery cannot be driven, we can discuss the available recovery options. If you have a suitable garage, we can arrange delivery of the engine for fitting there.
