Disadvantages of the A18XER engine

  • The ignition system delivers the most problems, especially the module with coils;
  • Oil cooler leaks are also common, changing the gasket usually helps;
  • In this generation of motors, phase regulators have become more reliable, but sometimes they break;
  • The weak point of the engine is an unreliable crankcase ventilation system;
  • Do not forget about adjusting valve clearances by selecting measuring cups.
