The Land Rover 3.0 TDV6 and SDV6 diesel engines are used in popular North American and global platforms including Discovery 4 / LR4, Range Rover Sport, Range Rover and related Jaguar Land Rover applications. This guide helps buyers identify the right rebuild parts, confirm fitment and avoid ordering parts by engine size alone.
Common engine codes
Before buying parts, confirm the exact engine code and vehicle platform. The most searched applications include 306DT and 306DTA engines. These engines may share many parts, but crankshaft, bearing, oil pump, timing and ancillary fitment should still be checked by VIN and OEM part number.
Key rebuild parts to verify
- Crankshaft and main bearings
- Connecting rod bearings
- Oil pump and oil pickup
- Timing chain components
- Turbocharger oil lines
- Cooling system parts
- Gaskets, seals and hardware
Why VIN fitment matters
Land Rover parts catalogs often separate compatibility by model year, chassis code, market and engine variant. A Discovery 4 / LR4 2010-2016 L319 and a Range Rover Sport L320 may use related diesel engine components, but final compatibility should be confirmed before purchase.
Crankshaft and bearing notes
For 3.0 TDV6 / SDV6 rebuilds, the crankshaft should not be treated as an isolated part. Main bearing condition, oil pressure, oil cooler contamination, oil pump condition, block alignment and injector condition can all affect rebuild reliability. When ordering crankshaft or bearing parts, send the VIN, engine code and any visible OEM numbers.
How to order the right parts
Use the model categories on this site to start with the vehicle platform, then search by OEM number, VIN, engine code or part category. For uncertain applications, request a fitment check before checkout.
