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.
