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.
