Reliable Engines, Rebuilt to Last
Land Rover & Jaguar Engine Rebuilding | OEM-Spec Reconditioning
Is your TDV6 knocking, your SDV6 rattling, or your Ingenium burning oil? Don’t scrap the vehicle before you know whether a proper strip-down rebuild can save it.
Since 2009, JLR Engine Specialists has rebuilt over 1,000+ Land Rover, Range Rover and Jaguar engines to OEM-spec or OEM+ standards from our Billericay workshop, with nationwide collection and delivery available.
Our IMI-certified technicians rebuild engines using only OEM-grade components from brands such as Mahle, Kolbenschmidt, INA, Gates, Victor Reinz, Elring and Glyco, depending on engine code, VIN compatibility and supplier availability at the time of rebuild.

Which Engines Do We Rebuild?
We rebuild failed, worn or damaged engines across the key JLR range, plus selected BMW and Mercedes diesel units that share similar rebuild requirements and failure patterns. Final parts specification always depends on engine code, VIN, build date, emissions version and inspection findings.
Range Rover
- 3.0L V6 diesel
- 4.4L V8 diesel
- 5.0L V8 petrol AJ133
- Sport, Vogue, Velar & Evoque
- Standard and performance variants
Jaguar
- AJ126
- AJ133
- AJ-V6 / AJ-V8
- Ingenium petrol / diesel
- XF, XE, F-Pace, F-Type, XJ
BMW & Mercedes
- N47
- N57
- B47
- OM651
- OM642
We also service selected BMW and Mercedes engines where a full OEM-spec rebuild is a better value option than dealer replacement.
OEM parts note
We always describe parts as OEM, OEM-grade or OE-spec because chain kits, bearings, ring packs, gasket sets, oil pumps and seals can vary by model year and supplier availability. A typical rebuild may use components from Mahle, Kolbenschmidt, INA, Gates, Victor Reinz, Elring and Glyco, with exact references confirmed only after VIN check and strip-down inspection.
Our 7-Step Engine Reconditioning Process
This is where rebuild quality is won or lost. We document, inspect, machine, measure and test properly so you are not paying for a cosmetic tidy-up dressed up as a rebuild.
Vehicle Diagnostics & Compression Test
Before removal, we run a full OBD scan, compression test and borescope inspection. You receive a clear video report so the rebuild recommendation starts with evidence.
Engine Removal & Strip-Down
Your engine is removed and fully disassembled in a clean working environment. Every major component is tagged, measured and inspected rather than guessed at.
Ultrasonic Cleaning & Crack Testing
Reusable parts are degreased and cleaned properly. Cylinder heads and blocks are crack-tested so hidden damage does not make it back into the finished engine.
Precision CNC Machining
Cylinder bores are honed to tolerance, heads are skimmed where required, and valve seats and guides are corrected as needed. This stage is what separates a lasting rebuild from a short-term patch.
Component Replacement
We install new piston rings, bearings, timing chain kit, gaskets, seals, oil pump and water pump where included in the approved scope. We use OEM-spec parts only, never the cheapest unknown aftermarket option.
Reassembly & Bench Testing
Reassembly is completed with calibrated torque tools and proper sequence control. Oil and coolant circuits are pressure-tested before the engine leaves the bench.
Dyno Test & Road Test
Once fitted, the ECU is reset and the vehicle is tested for driveability, power delivery and fault-free operation. We then carry out a real-world road test so the rebuild proves itself under load, not just on paper.
What’s Included in Our Engine Rebuild Price?
We keep the scope clear so you know what is included in a standard serviceable-core rebuild and what is optional. That makes quotes easier to compare against dealer replacement and against cheap rebuilders who hide the real parts list.
Included
- Full strip-down and inspection.
- CNC machining including honing and skimming where required.
- New piston rings, bearings, gaskets and seals.
- New timing chain kit and tensioners.
- New oil pump and water pump in the standard approved rebuild scope.
- 12-month unlimited mileage warranty.
- VAT included in listed prices.
Not included as standard
- Turbochargers, though these can be rebuilt or replaced at the same time.
- Fuel injectors, though testing and replacement can be added.
- Ancillary components such as alternator, starter motor and A/C compressor.
- Major hard-part damage outside a standard serviceable core, such as a cracked block or unrecoverable crankshaft.
Example OEM-spec references
Where applicable, we fit OEM or OEM-grade components from recognised manufacturers rather than anonymous budget kits. Example part references can include items such as Mahle ring sets on selected JLR applications, but the exact part numbers are always matched to VIN, engine code and inspection findings before authorisation.
Engine Rebuild Pricing
These figures are realistic guide prices for standard rebuilds on serviceable core engines. Final fixed-price quotation follows inspection, not guesswork.

Price Estimate Disclaimer: All prices are guide estimates for standard rebuilds on a serviceable core engine. Final cost may vary based on diagnostic findings such as cracked heads, damaged crankshafts, block damage, injector failure or turbo contamination. We provide a fixed-price quote after inspection so there are no surprises.

Frequently Asked Questions
Strong rebuild pages need direct answers on time, cost, warranty and whether a rebuild is even viable. Keep this section visible for users and structured for search.
Most rebuilds take around 7 to 10 working days once the vehicle is in, stripped and approved. Timing can change if we find major hard-part damage or if additional work such as turbo, injector or DPF-related cleaning is needed.
We assess that after diagnostics and strip-down. If the block is cracked beyond recovery or the core is not serviceable, replacement can be the better route, but many TDV6, SDV6 and Ingenium failures are rebuildable when caught in time.
Yes. We offer nationwide collection and delivery across mainland UK, so you do not need to be local to Essex to use our rebuild service.
Our standard rebuild warranty is 12 months with unlimited mileage, covering parts and labour within the agreed terms of the repair.
A correctly rebuilt and fault-free engine should meet the required emissions and driveability standards for MOT compliance, assuming there are no separate failures elsewhere on the vehicle.
Yes. Please visit our financing page for the latest payment options and eligibility details.
We rebuild using OEM, OE-spec or OEM-grade components depending on the exact application and approved scope. That means we prioritise reputable manufacturers and correct specification rather than marketing labels alone.
We stop, document the findings and update the quote before proceeding. That is exactly why a proper inspection stage matters on complex engines like the TDV6, SDV6, AJ126 and Ingenium families.
