Disadvantages of the X12XE engine

  • This is a reliable unit, but it does not tolerate low-quality oil and long replacement intervals.
  • Therefore, on specialized forums they complain about coking of the lubricant and sticking of hydraulic compensators.
  • The oil pump is small and its performance often drops after a mileage of 200,000 km.
  • The timing chain does not have a long service life and often requires replacement before 100,000 km.
  • The weak points of this power unit also include the thermostat and the ignition module.
