Disadvantages of the Land Rover 448DT engine
- This motor is considered the most reliable in the line, but it can bother you over small things;
- In diesel engines of the first years, there is a defective pipeline for draining oil from the turbine;
- Even on the first engines, the drive belt breaks due to the displacement of the tension roller;
- Air pipes cause a lot of trouble, they simply tan and crack;
- Also, a heat exchanger, an oil pump and a front crankshaft oil seal often leak here.
