Disadvantages of the Jeep EXN engine

  • Most of the complaints on the specialized forums are related to leaks and especially to the oil cooler.
  • The pipes are not reliable and regularly burst, and all the hoses still leak.
  • Due to the fault of bad fuel, the capricious high-pressure fuel pump fails and begins to drive chips.
  • There were cases when, due to a leaky corrugation, the turbine overheated and failed.
  • The weak points of the unit also include a particulate filter and an EGR system cooler.
