Disadvantages of the VQ20DE engine

  • Often complain about floating speed due to contamination of the idle valve;
  • For even engine operation, periodic adjustment of the throttle position sensor is also required;
  • Since there are no hydraulic compensators, the thermal clearances of the valves also need to be adjusted;
  • By about 200 – 250 thousand kilometers, a timing chain kit will need to be replaced;
  • The engine is afraid of overheating, constantly monitor the condition of the cooling system;
  • Power units with high mileage almost always suffer from oil burn.
