Disadvantages of the MRA8DE engine
Owners of vehicles with such motors typically lament their oil consumption online;
The alternator belt whistle and the knocking of improperly adjusted valves rank second;
Third place goes to floating engine speeds caused by dirt on the throttle; the timing chain rumble, which can extend up to 120,000 kilometers; and, very infrequently, block head cracking during bolt and candle tightening.
