Disadvantages of the X25XE engine

  • Grease often oozes from under the valve cover and sometimes penetrates into the spark plug wells;
  • The oil cooler is also not famous for its tightness, from there the lubricant enters the antifreeze;
  • The oil receiver is close to the sump and blocks it in case of any damage;
  • The timing belt resource is approximately 60,000 km, and if it breaks, the valves will bend 100%;
  • This engine is afraid of the cold and in severe frost there will be problems with starting.
