Disadvantages of the Z24SED engine

  • The motor has no problems with reliability, the only negative is that it is afraid of the cold;
  • Owners usually complain about high fuel consumption and strong vibrations at work;
  • The rear crankshaft oil seal has a low resource, it often flows already at 70,000 km;
  • According to the manual, the timing belt is changed at 120,000 km, but I advise you to halve the interval;
  • The remaining breakdowns are associated with oil leaks and a clogged crankcase ventilation system.
