Disadvantages of the Z17DTH engine
Rubber injector sleeve seal leaks are the most well-known engine issue; low-quality antifreeze can occasionally corrode these sleeves and the heat exchanger;
The Common Rail fuel system’s various malfunctions come in second;
As with any diesel engine, the diesel particulate filter and EGR valve need to be cleaned on a regular basis. The turbine frequently fails between 150 and 250 thousand kilometers.
