Land Rover is meant to climb, tow and tour without complaint, yet even the most capable Discovery 4 can suffer an engine failure like a crank break or timing belt snap. When that happens, you do not have to scrap this great vehicle. Royal Rebuilds keeps thousands of Land Rover Discovery 4 vehicles moving with carefully rebuilt or low mileage used and reconditioned engines. We have a big in house stock of Land Rover Discovery engines, and we stock the complete engine for 3.0 TDV6 and SDV6 units, including the popular 306dt engine code. We offer full in house machining for your block, and back every job with a clear up to 12-month warranty for peace of mind.
From the moment you come to our state of the art garage, you deal with engine specialists with 25 years’ experience. We scanned your vehicle with dealer level diagnostics and were given a health check with thorough engine testing checks before any work began. Whether you choose a supply only engine, a quality reconditioned unit fitted, or a rebuild of your original car engine, the package for an engine supplied and fitted always includes fresh filters, premium oil and a test when the job is complete. We work mostly on the Jaguar Land Rover engine models, so every Discovery 4 that rolls into our shop for a fit service benefits from specialist jigs, dedicated TDV6 tooling and parts kept on the shelf. Services range from a quick interim oil change after fitting to a comprehensive brake fluid, filter and health check package. Because our workshop is purpose built, turnaround times stay short and quality control stays in our hands from first inspection to final valet.
History of the Land Rover Discovery 4
The Land Rover Discovery 4 was officially launched in September 2009. It boasts a completely redesigned interior in comparison to its predecessor. It also came with updated external styling at the nose and tail. The TDV6 2.7 litre engine (engine code 276dt) was borrowed from the Discovery 3; however, it also came with the 3.0l TDV6 diesel engine. Later, the 2.7 litre was replaced by the 3.0 litre SDV6 in 2011. This replacement also reduced exhaust emissions, thanks to its eight speed automatic gearbox. Additionally, a 3.0 litre V6 engine was also offered; however, the V6 petrol & V8 petrol engines weren’t made available in the UK. Several well-furnished, limited edition models were presented, including the Landmark, Black & White, HSE Luxury, and Graphite. Although all are nice models yet none of these surpasses the regular HSE trim level. We stock engines for all Land Rover models, from the Discovery 4 to the L494.

What engine is in a Discovery 4, and when should it be replaced?
For the Discovery 4 engines technical details, it launched in 2009 with Land Rover’s 2.7 litre TDV6 and soon moved to the twin turbo 3.0 TDV6/SDV6 diesel family. While these are the most common, other engines available include the 2.0 TDI. An engine replacement becomes the smart option when the crankshaft breaks, a timing belt fails, or low oil pressure damages the bearings or scores a cylinder wall. If your engine knocks, loses oil pressure, drops power or shreds its timing belt, it is usually cheaper and safer to rebuild or swap the whole unit instead of chasing endless small repairs. Drivers often decide to act at 100,000 miles or sooner if they tow heavy loads.
What are the most common Discovery 4 engine problems?
- Crankshaft breakage
- Main bearing wear
- Snapped front or rear timing belts
- Turbo wear from dirty oil
- EGR cooler leaks
- Oil leakage
- Injector seal blow-by
Our engine reconditioning program tackles all of these at once: fresh crank, belts, bearings, cleaned injectors, and pressure tested coolers. Fixing them together keeps the cost down and reliability up.
Is the 3.0 TDV6 diesel engine reliable enough to buy reconditioned?
Yes, if the job is done right. A solid reconditioned TDV6 is stripped to its bare block, cleaned, machined and rebuilt with new pistons, bearings, gaskets, timing belts and a stronger, updated crankshaft. A properly remanufactured TDV6 can run as strongly as a brand new crate engine. Many of our customers have run 100,000 miles on a reconditioned unit without trouble.
How much does a Discovery 4 engine rebuild cost, and what’s included?
Royal Rebuilds issues a tailored written quote, often saving you significantly compared to a main dealer's new engine, so owners only pay for the work their vehicle needs. A typical rebuild covers strip down, machining, new crankshaft, pistons, rings, bearings, oil pump, timing kit, head work, reassembly, fluids and an interim, major or comprehensive service package as listed on our website. Collection and redelivery can be added, and every Disco 4 recon engine leaves with up to 12 months.
Why do TDV6 engines fail, and how is the crankshaft fixed?
The original crank is narrow between journals, so repeated load cycles can start a fine crack that spreads without warning. This is a primary cause of TDV6 engine failure. Long oil intervals or the wrong viscosity make the problem worse by starving the centre bearings. During a rebuild, we install the latest OE spec crank with polished radiused journals, fit matched bearings and balance the rotating assembly. A new oil pump and a stricter service schedule will fully resolve the issue.
Does Royal Rebuilds supply and fit Discovery 4 engines?
We understand that everyone has busy schedules to follow and commitments to keep, and that is why we offer a fast supply, pickup and delivery service where we can arrange a pickup of your vehicle from wherever you instruct us to, and our expert mechanics fit the engine to perfection. We run the necessary tests on the engine, like compression tests and running tests, and if we are satisfied, then we deliver the vehicle to your doorstep. We'll return your LR Disco 4 ready for the road.
Is a 12-month warranty enough for a rebuilt Discovery 4 engine?
A full year of cover matches or beats the industry standard for remanufactured units. Because we use top quality parts, replace or machine every high stress part and test each engine before installation, warranty claims are rare, as most issues show within the first few thousand miles, if they show at all. If a problem does arise, you deal with the same team that built the engine; no third party insurers, no long waits.
Does the Discovery 4 3.0 TDV6 have a timing belt or chain?
The 3.0 engine uses a belt at the front for the camshafts and a smaller secondary belt at the rear that drives the high pressure fuel pump. Both are replaced during our rebuild or major service, along with a new tensioner, idlers and auxiliary belt.
What does SDV6 stand for, and which Discovery engine is best?
SDV6 means Sequential Diesel V6. It is the uprated version of the TDV6 with revised mapping and, in later years, an eight speed gearbox; power rose from about 241 hp to 255 hp. Apart from the extra shove, the hardware is the same, so a freshly rebuilt TDV6 or SDV6 will give similar long term reliability. No matter your choice, we have the quality engines for your Land Rover.
