Disadvantages of the ENE engine
The Delphi piezo injectors on the first-generation engines were replaced by a revocable company;
The fuel system’s metering valve in the rail is another vulnerability;
The motor could be in danger if the variable displacement oil pump fails;
The intake manifold should be the first place to look for air leaks because it frequently cracks. This diesel engine also frequently experiences antifreeze leaks from the thermostat and pumps.
