Engine had a knock that kept getting worse. Full rebuild sorted it completely, and the detail they went into with the inspection report was impressive.

Detailed Overview
Complete Engine Reconditioning for Range Rover and Land Rover
Our engine rebuild service, based in Grays, Essex, covers everything from initial strip-down and component inspection through to precision machining and reassembly.
We work to the same tolerances Jaguar Land Rover specifies at the factory, checking crankshafts, cylinder heads, bearings and seals against exact measurements rather than estimating wear.
Every part that doesn't meet spec is replaced with OEM-quality components, and every rebuilt engine is tested thoroughly before it goes back into your vehicle, giving you confidence the job has been done properly from the inside out.
Confidence Built Into Every Rebuild
We back every engine rebuild with a clear warranty, because a job of this scale should give you long-term peace of mind, not just a temporary fix.
Measured, Not Assumed
Every component is measured against factory tolerances before reassembly, so worn parts are identified accurately rather than replaced or retained on guesswork.
Warranty on Parts and Labour
Each rebuilt engine is covered by a written warranty on both components and workmanship, giving you assurance the rebuild will perform as expected.

Was quoted a full replacement engine elsewhere. These guys rebuilt mine instead, saved me thousands, and it runs better than it has in years.

Specialist Range Rover And Land Rover Repair Process
Process SectionOur Step-by-Step Engine Rebuild Process
A proper engine rebuild depends on precision at every stage, from the initial strip-down through to final reassembly. We follow the same structured process on every Range Rover and Land Rover engine that comes through our workshop.
Step 1 — Full Strip-Down and Inspection: The engine is completely stripped and every component is inspected and measured against factory tolerances to identify wear or damage.
Step 2 — Precision Machining: Cylinder heads are skimmed and crankshafts reground or replaced as needed, restoring components to exact manufacturer specifications.
Step 3 — Reassembly With Quality Parts: The engine is rebuilt using OEM-quality gaskets, seals and wear components, following torque settings and procedures set out by JLR.
Step 4 — Testing Before Refitting: Before refitting, the rebuilt engine is tested for compression and leaks, confirming it meets performance standards prior to installation.

PRECISION ENGINEERINGPRECISION MACHINING MATCHED TO FACTORY STANDARDSFACTORY STANDARD MACHINING
An engine rebuild is only as good as the measurements behind it, which is why we machine every component to the exact tolerances Jaguar Land Rover specifies for that engine variant. Cylinder heads are skimmed to restore a flat sealing surface, crankshafts are reground or replaced where wear exceeds acceptable limits, and every bearing clearance is checked rather than assumed.
This precision matters because even small deviations from factory tolerances can shorten an engine's lifespan significantly. Our machining process is designed to eliminate that risk entirely.
WHY A REBUILD OFTEN BEATS A REPLACEMENTREBUILD VS REPLACEMENT
Many Range Rover and Land Rover owners assume a failing engine automatically means an expensive replacement unit, but a full rebuild frequently delivers the same reliability at a considerably lower cost.
Because we strip the engine completely and machine or replace every worn component, the rebuilt unit performs to the same standard as a factory-fresh engine, without the premium price tag of sourcing a new or replacement unit. For many faults, particularly wear-related issues rather than catastrophic damage, a rebuild is simply the smarter financial decision.
COST-EFFECTIVE SOLUTIONSMACHINING PRECISION THAT PROTECTS LONG-TERM PERFORMANCE
Every cylinder head we skim and every crankshaft we regrind is measured against strict factory tolerances, not general estimates. This level of precision ensures proper sealing, correct bearing clearances and smooth engine operation once reassembled.
It's this attention to exact measurements, rather than approximate fitting, that determines whether a rebuilt engine lasts years or fails again within months.
QUALITY COMPONENTS BUILT TO LAST THE DISTANCE
We rebuild using OEM-quality gaskets, seals, bearings and wear parts throughout, avoiding budget alternatives that compromise durability.
Combined with correct torque settings and assembly procedures matched to your specific engine variant, this ensures the finished rebuild performs reliably under real-world driving conditions, not just on a test bench.
COMMON ENGINE QUESTIONS
Straight Answers, No Jargon
A full rebuild includes complete strip-down and inspection, precision machining of components such as the cylinder head and crankshaft, and reassembly using OEM-quality parts. Every stage is measured against factory tolerances, and the finished engine is tested before it's refitted to your vehicle.
