Disadvantages of the EZA engine

  • These engines are not considered problematic, but they are characterized by high fuel consumption;
  • In this version of the engine, there is also no MDS system, so it is the most reliable in the line;
  • On power units of the first years of production, there were cases of valve seats falling out;
  • Sometimes the engine can make strange sounds in operation, nicknamed Hemi ticking;
  • Also, two candles per cylinder are used here, it is worth considering this when replacing.
