  • Savings on maintenance and frequent overheating lead to scoring;
  • The use of low-quality oil often results in the sound of hydraulic lifters;
  • Monitor the condition of the timing belt, as with its breakage, the valves most often bend;
  • Lubrication leaks are also regularly encountered, and especially at the junction of the motor with the gearbox.
