Discovery 4 engine parts
Internal and external engine parts for Land Rover diesel and petrol engines, from the 300Tdi and Td5 to the TDV6, SDV6, SDV8 and Ingenium units.
What is specific to the Discovery 4
The Discovery 4 was sold in South Africa with 2 different engines. Internal parts, gaskets, timing components and sensors are specific to each, so the engine code decides the part before anything else.
Have this ready when you enquire
- The 17-character VIN from your licence document, which identifies your exact L319 (sold here 2009–2017) and its build.
- The engine code or number, because this model was sold with the 3.0 TDV6 turbodiesel and 3.0 SDV6 twin-turbodiesel.
- A photo of the old part or its part number, if you can get to it.
| Engine | Code / family | Fuel |
|---|---|---|
| 3.0 TDV6 turbodiesel | TDV6 | Diesel |
| 3.0 SDV6 twin-turbodiesel | SDV6 | Diesel |
Known Discovery 4 engine parts faults
Crankshaft bearing concern on pre-2012 diesels
Jaguar Land Rover South Africa confirmed in 2015 that V6 diesels built before 2012, including the Discovery 4, could suffer main bearing failure. It said engines built from 2012 use a new bearing design; that is the manufacturer’s statement, not a guarantee for any individual engine, so check the build date and service history.
Timing belt service is critical
The 3.0 V6 diesel uses a timing belt. If it is not replaced on schedule and snaps, the pistons can hit the valves and the engine is badly damaged.
Parts commonly needed for the Discovery 4
Parts commonly needed on the Discovery 4 include air suspension components (compressors, air springs, valve blocks, height sensors), timing belt kits for the 3.0 diesel, intake manifolds, EGR valves, turbochargers and mass air flow sensors. Replacement engines are often needed after crankshaft or timing failures. Owners planning ahead also order front and rear differential parts and suspension bushes at the same time as a timing belt service, because the vehicle is already in the workshop and labour on this model is expensive.
Replacing the whole unit? A complete unit may cost less than rebuilding one on an older Discovery 4. See cylinder heads for sale or turbochargers for sale .

Discovery 4 engine parts questions
How important is the timing belt on a Discovery 4 diesel?
Very. The 3.0 V6 diesel uses a timing belt, and a local cars.co.za buyer's guide singles out the cambelt service as an important cost to budget for. If the belt snaps, the pistons can hit the valves and cause severe engine damage.
What does a cracked intake manifold do on a Discovery 4?
The 3.0 V6 diesel uses a plastic intake manifold that can crack or leak at its gasket, which commonly triggers a restricted performance warning, especially under load. It is one of the known faults listed for the Discovery 4 in local used-buying advice.
How do I know which engine my Land Rover has?
Start with the VIN on your licence disc and in the windscreen corner. The vehicle's registration papers, the service book and the engine number stamped on the block also identify it. Model names alone are not enough: a Discovery 4, for example, came with different diesel and petrol engines, and a Defender could have a 300Tdi, Td5 or Puma diesel depending on its year. Send the VIN with your quote request so the part can be matched to the engine code.
Should I repair my Land Rover engine or replace it with a complete unit?
It depends on what failed. A leaking gasket, a worn timing kit or a faulty injector is a repair job. Bottom-end damage, such as a spun bearing or a broken crankshaft on a V6 diesel, often makes a complete replacement engine more practical than a rebuild, because the block, crank and turbo may all need attention. Get a proper diagnosis first, then compare the cost of a rebuild kit plus machining against a complete engine.
