Disadvantages of the X17DTL engine
The unit is renowned for its good repairability and unpretentious approach to diesel fuel quality;
Fuel pump malfunctions are the most common cause of starting issues;
The turbine quickly begins to run on oil, and fixing it is rather costly;
The timing belt is a small resource, and the motor is at risk if it breaks or jumps;
Oil consumption is typically caused by a leak in the crankcase ventilation or crankshaft oil seal.
