Specialist JLR engine rebuilds and repairs, just a few miles from Rainham in Grays.
Don't Have Reg..?
Range Rover Garage is an independent JLR specialist working exclusively on Range Rover, Land Rover and Jaguar engines. Being so close to Rainham, we offer owners a convenient main dealer alternative, with factory-trained engineers who rebuild and repair Ingenium, TDV6, SDV6 and TDV8 engines across Defender, Discovery and Range Rover.
Our workshop is in Grays, just a few miles east along the A13, so you can call in as a walk-in or book collection from across RM13, including Wennington, plus Elm Park and Upminster. Diagnostics and an itemised quote come first, and most rebuilds take 7 to 14 working days.
Mention Any Overheating Episodes
If the temperature gauge has spiked even once, tell us when booking. A single overheating episode can warp cylinder heads or weaken a head gasket, and knowing about it helps our engineers decide which checks to prioritise.
A knock that worsens under load, falling oil pressure or blue smoke at start-up usually indicate wear that only a Range Rover engine rebuild resolves.
Every engine is stripped, ultrasonically cleaned, machined and rebuilt with genuine OEM parts, then pressure-tested and run under load before sign-off at our workshop.
Overheating, coolant loss with no visible leak or a creamy residue under the oil cap often point to head gasket failure on Land Rovers.
We pressure-test the cooling system, check the cylinder heads for warping and cracks, and repair before further engine damage develops.
When repairs would cost more than your Defender is worth, we supply and fit tested reconditioned engines matched to its engine code.
Reconditioned units carry six months' warranty, with extended dealer-level cover of up to 24 months available.
Rainham is one of the closest areas to our Grays workshop, so specialist JLR engine care is only a short drive away. You can drop your vehicle in during opening hours or let us collect it from home or work. Our engineers are factory-trained on Range Rover, Land Rover and Jaguar engine systems, fit genuine or OEM-grade parts tested to manufacturer specifications and agree an itemised quote with you before any work begins, with direct updates from our team throughout.
Collection Across Rainham and RM13
Our Services
Beyond rebuilds and replacements, our engineers repair specific engine faults on Range Rover, Range Rover Sport, Evoque, Velar, Vogue, Discovery and Defender models for drivers across Rainham and Havering.
A warning light on the A1306, rough running or sudden limp mode can each have several possible causes. Our engineers read live data with dealer-level equipment, confirm the fault physically before quoting, and offer same-day diagnostics on most bookings.

A brief rattle on a cold start is among the best-known Range Rover common faults and usually signals a stretched timing chain. We replace the chains, guides and tensioners together, helping prevent jumped timing and serious valve damage.

Sluggish acceleration, a high-pitched whistle or blue smoke under load can point to a failing turbocharger. Before fitting a replacement, we check oil supply, boost pipework and actuator, so the new unit is not let down by the original fault.

Oil leaks, injector faults, sticking EGR valves and failed sensors can often be repaired without a rebuild. Our engineers correct the specific fault, keeping costs proportionate, and test the engine thoroughly before your vehicle is returned to you.

For higher-mileage Discovery, Freelander and older Range Rover models, a tested second-hand engine can be the most practical way back on the road. We confirm full compatibility first, and every engine swap includes one month's warranty as standard.

Some earlier Land Rover engines rely on a timing belt that must be renewed at the manufacturer's recommended interval. We carry out scheduled and emergency belt changes, helping you avoid the bent valves and piston damage a snapped belt causes.

"My Velar's engine light came on outside Upminster and the idle became uneven. Their diagnostics found a leaking intake manifold gasket rather than an internal fault, and they explained the readings clearly before giving me a price."
Kerry Watts
"Dropping my Jaguar F-Pace in was easy from Rainham, and the timing chain quote was explained line by line at the counter. I had a call when parts arrived and another when it was ready."
Raj Mistry
"Even though Grays isn't far from Elm Park, collection suited me better with work. They picked up the Defender 90 on the agreed morning, kept me posted and returned it the following week with the paperwork explained."
