Disadvantages of the Z20S engine

  • This engine is not considered problematic, on specialized forums it is more often praised than scolded;
  • Like any modern common rail diesel, this one also does not like bad diesel fuel;
  • The weakest point of the fuel equipment is most often the injectors;
  • The timing belt has a small resource of 50 – 60 thousand km, and when it breaks, the valve bends.
