Land Rover Discovery 4 (L319 / LR4) EnginesReconditioned, Used & Rebuilt Supply and Fit Across the UK
The Discovery 4 — sold as the LR4 in North America — built directly on the acclaimed L319 platform and refined everything that made the Discovery 3 great. Better technology, improved refinement, and a broader engine range made it one of the most capable and desirable large SUVs of its era.
What it didn't escape, however, was the reality that complex, high-performance engines eventually need specialist attention.
At Vogue Technics in Grays, UK, we supply, rebuild, and fit Land Rover Discovery 4 (L319 / LR4) engines across every variant — from the 3.0 TDV6 and SDV6 diesel through to the 4.4 V8 petrol. We understand these engines in genuine depth, and we deliver solutions that are properly warranted, honestly priced, and built to perform.

Used & Reconditioned Land Rover Discovery 4 Engines — All Variants, Full Coverage
We stock a comprehensive range of Discovery 4 engines to suit every requirement and budget. Whether you need a direct replacement for a seized SDV6 or a fully rebuilt V8 petrol unit, we source, build, and supply the right engine for your specific model, year, and specification.
3.0 TDV6 & SDV6 Diesel Engine — Reconditioned & Used Units
The 3.0 TDV6 and SDV6 are the engines most Discovery 4 owners in the UK are running — and they're the units we work on most frequently. Both deliver strong performance and real-world usability when properly maintained. When they aren't, they develop a familiar set of problems that need experienced hands to resolve correctly.
Our Discovery 4 3.0 diesel engine services include:
- Fully reconditioned TDV6 and SDV6 engines rebuilt to OEM specification
- Used Discovery 4 diesel engines — tested, documented, and ready to fit
- SDV6 engine for sale with warranty — supply only or complete supply and fit
- 3.0 TDV6 engine overhaul and full strip rebuild service
- Engine oil specification and capacity guidance for every variant
4.4 V8 Petrol & 4.6 V8 Engine Supply and Rebuild
For Discovery 4 owners running the 4.4 litre V8 petrol — and for those with earlier 4.0 or 4.6 V8 variants — we offer complete engine supply, rebuild, and fitting services. These are characterful, capable engines that reward proper care and quality rebuilding.
Our V8 services cover:
- Land Rover Discovery 4.4 V8 engine rebuild and replacement
- Discovery 4.6 engine rebuild kit supply and full assembly
- 4.0 V8 engine supply, rebuild, and fit — all model years
- Reconditioned V8 units with full warranty cover

Supercharged & Performance Engine Options
For owners looking to upgrade beyond standard specification, we also provide consultations and sourcing support for Discovery 4 supercharged engine options and higher-output conversions. Contact our Grays team to discuss what's achievable for your specific vehicle and intended use.
Looking for extended coverage?
We also offer up to 24 months warranty, sourced directly from main dealers. Please note, this option comes at a higher cost due to the extended protection and premium coverage.
Discovery 4 Engine Faults, Diagnostics & Repair — From Warning Light to Full Rebuild
Engine problems on a Discovery 4 rarely announce themselves politely. A warning light appears, a knocking noise develops, or the vehicle simply loses power without clear explanation. Getting to the root cause quickly — and accurately — is everything.
Engine Warning Light, System Fault & Oil Leak Diagnosis
Our same-day Discovery 4 engine diagnostics service in Grays uses specialist equipment and genuine hands-on knowledge of TDV6 and SDV6 engine management systems to identify faults accurately and efficiently.
Common Discovery 4 engine problems we diagnose and resolve:
- Engine warning light and engine system fault codes
- Discovery 4 engine knocking noise and engine ticking
- Engine oil leak — including rocker cover, sump, and turbo feed pipe
- Engine oil consumption on V8 and diesel variants
- Engine failure and engine seizure assessment and recovery
- Low battery and parasitic drain affecting engine start
Engine Seizure & Failure Recovery
A seized Discovery 4 engine is one of the most stressful situations a Land Rover owner faces. It typically happens without much warning — and the decisions made immediately afterwards significantly affect the outcome and the cost.
Our team assesses every seized or failed engine thoroughly before making any recommendation. In some cases, internal damage is less severe than it appears. In others, replacement is clearly the right answer. Either way, you'll get an honest assessment with clear options — not a rushed upsell.
Rebuild vs Replacement — Clear, Honest Guidance
We assess every Discovery 4 engine on its own merits. A Land Rover Discovery 4 engine rebuild — when the internal condition justifies it — delivers a properly restored unit at a fraction of new engine cost. When replacement is more appropriate, we source the right unit and fit it correctly.
You'll always know the cost of both options before committing to either.
Discovery 4 Engine Swaps, Remaps & Performance Upgrades
The Discovery 4 platform supports a meaningful range of engine swap and performance upgrade options — and our Grays workshop has the capability and experience to carry them out to a proper engineering standard.
Engine Swap Options — Toyota 4.7, Bosch 4.6 & Alternative Conversions
We handle Discovery 4 engine swap consultations across a range of options — including Toyota 4.7 engine swap builds, Bosch 4.6 engine conversions, and alternative diesel swap projects. These are complex, precision jobs that demand proper planning and genuine engineering knowledge.
Every swap project is assessed individually before any work begins. We advise on compatibility, required fabrication, wiring harness considerations, and realistic costs — so you have a complete picture before committing.
Engine Remap & Tuning — TDV6 and SDV6 Performance
The Discovery 4 3.0 TDV6 and SDV6 respond well to a properly executed engine remap — delivering meaningful gains in torque and power output without compromising long-term reliability when carried out by specialists.
We offer Discovery 4 engine tuning and remap services as part of our broader engine performance offering.
