The 306DT internal combustion engine has established itself as an engine with an increased resource and violent temper. The diesel engine has 6 cylinders, a cast iron block and aluminum cylinder heads.
6 cylinders are arranged in a V-shape. 24 valves, 2 camshafts and timing belt drive. Naturally, the offspring of the Range Rover received a Twin-Turbo supercharging system.

Advantages, Disadvantages and Problems of the 306DT engine
Advantages
- Reliability;
- An impressive resource and a variety of firmware;
- DOHC system.
Disadvantages
- Expensive repairs;
- Doubtful working resource of components;
- The timing belt is likely to fail quickly when the engine is running under heavy loads;
- Coolant leak (factory defect).
Typical malfunctions
- Used air filter and oil filter – power drops;
- Crankshaft split – perhaps one of the main engine problems, which has become very widespread;
- Wear on the connecting rod bearings of the connecting rod journals – restriction of oil flow due to a clogged / used filter;
- Front crankshaft oil seal – incorrect fit of the oil pump from the factory;
- At low temperatures, the crankcase ventilation line freezes;
- Imbalance in the operation of the injectors – a direct path to overhaul, when the injectors began to supply an enriched fuel mixture. This will instantly lead to overheating of the working cylinder and even burnout of the filter.
Tuning prospects
Recoil varies between 211 and 340 forces. It all depends directly on the control unit software and the selected parameters. Also, do not forget to control the oil level and carry out its timely replacement. The 306DT engine is one of the most dynamic and opens up at medium speeds. Therefore, it is often forced only by reprogramming.
