Discovery · L319 · 2005–2009
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.
The Discovery 3 was sold in South Africa with 3 different engines. Internal parts, gaskets, timing components and sensors are specific to each, so the engine code decides the part before anything else.
| Engine | Code / family | Fuel |
|---|---|---|
| 2.7 TDV6 turbodiesel | TDV6 | Diesel |
| V6 petrol | — | Petrol |
| V8 petrol | — | Petrol |
Land Rover V6 diesels made before 2012 can suffer crankshaft main bearing failure. In a 2015 IOL report Jaguar Land Rover South Africa confirmed the Discovery 3 was among the affected models, and one owner was quoted R260,000 to repair a 2008 Discovery 3.
A split in the large intercooler hose on the TDV6 loses boost pressure and puts the vehicle into restricted performance, usually with black smoke. Oil on the outside of the hose is a clue.
TDV6 owners regularly need EGR valves, intercooler hoses, turbochargers and cooling parts, and a TDV6 with a failed bottom end often becomes a replacement engine enquiry.
Replacing the whole unit? A complete unit may cost less than rebuilding one on an older Discovery 3. See cylinder heads for sale or turbochargers for sale .
Common causes are faulty EGR valves or a split main intercooler hose, both of which upset the air-fuel mixture. Inspect the large hose that runs down to the bottom of the intercooler for oil on the outside or a split. The Discovery 3 has two EGR valves and they tend to fail close together.
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.
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.
Share the VIN and engine number and the SparesBoyz parts team will check fitment before quoting.
