Jaguar & Land Rover Engine Rebuilds – Fixed Price, 12-Month Unlimited Mileage Warranty
Professional engine rebuilds in Billericay. Fully reconditioned, dyno-tested, with 12-month unlimited mileage warranty. UK-wide collection.
You've already identified the issue-whether it's internal wear, excessive oil consumption, or a seized unit. Now you need a trusted specialist who can rebuild your engine to last, not just install a cheap exchange unit with unknown history.
At JLR Engine Specialists Ltd, every engine rebuild is performed in-house at our Billericay workshop by technicians with over 8 years of dedicated Jaguar and Land Rover experience. We don't outsource. We don't cut corners. And we back every rebuild with a 12-month, unlimited mileage warranty-because we're confident in our work.
All rebuilds include ECU reset, adaptation, and road testing as standard. No hidden fees. No surprises.
Our Engine Rebuild Process: Precision Engineering, Not Guesswork
Unlike garages that bolt in used engines, we rebuild yours from the ground up-ensuring longevity, reliability, and seamless integration with your vehicle's systems.
Full Strip-Down & Inspection
Your engine is completely disassembled. We inspect the block, crankshaft, camshafts, and cylinder heads using precision tools-including bore scopes, micrometers, and pressure testers-to identify any hidden damage.
Machining & Strategic Upgrades
- Cylinder bores honed to exact OEM tolerances
- Crankshafts polished or reground if needed
- Heads pressure-tested and skimmed flat
Reassembly with Quality Components
We never reuse worn parts. Every rebuild includes:
Pre-Installation Dyno Testing
Before it returns to your vehicle, the engine runs on our test rig for 30+ minutes. We verify:
- • Stable oil pressure (minimum 30 psi at idle)
- • Compression balance within 10% across all cylinders
- • Smooth operation at all RPMs
Seamless Reinstallation & Calibration
- Engine fitted with new mounts and correct fluids
- Full ECU security access and adaptation
- Road test with live data logging
- Digital service report emailed within 24 hours
Why a Rebuild Beats a "New" Exchange Engine
Many customers are offered "tested" exchange engines-but these often come from crashed or high-mileage vehicles with hidden damage. Our rebuilds offer superior value:
| Factor | Exchange Engine | Our Rebuild |
|---|---|---|
| History | Unknown | Fully documented |
| Warranty | 30–90 days | 12 months, unlimited mileage |
| Reliability | High risk of early failure | Built to exceed original lifespan |
| ECU Compatibility | May require costly reprogramming | Seamless integration-no coding issues |
| Cost | £3,500–£5,000 + labour | Similar price, far more reliable |
