Disadvantages of the X18XE engine

  • This engine is considered reliable, and all its problems are solved simply and inexpensively;
  • To avoid floating speed, it is necessary to clean the idle speed control and the crankcase ventilation system;
  • The exhaust manifold often cracks, it is pointless to weld, you have to buy a new one;
  • Weak spot in the electrical part – camshaft position sensor;
  • The timing belt runs no more than 60,000 kilometers, and when it breaks, the valves always bend.
