Disadvantages of the SsangYong D23DT engine
- This is a reliable and durable pre-chamber diesel engine equipped with an in-line Bosch high-pressure fuel pump;
- The main thing is to monitor the condition of the cooling system, the cylinder head often cracks;
- Saving on oil here reduces the life of the fuel pump and hydraulic lifters;
- Other weak points include injector nozzles and glow plug wiring;
- At long runs, the turbine often fails or the timing chain is pulled.
