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.
