Disadvantages of the MR18DE engine
There have been instances of the cylinder head cracking when bolts or candles were tightened because of the thin walls;
The timing chain is at a high risk of being stretched after 150,000 kilometers; the most important thing is to not miss the moment;
Drivers frequently worry about the alternator belt’s whistle and the throttle’s quick contamination;
Since there are no hydraulic lifters, remember to periodically adjust the gaps. Nevertheless, the primary issue with the motor is the oil burner due to the occurrence of rings.
