Disadvantages of the SR20DET engine

  • If you do not save on oil, this motor quietly drives more than 300 – 350 thousand km;
  • Cheap oil clogs the channels, reducing the resource, especially for the turbine;
  • By about 200 – 250 thousand km, the timing chain often stretches and starts to rattle;
  • The reason for floating speed should be sought in the idle speed controller or mass air flow sensor;
  • Strong vibrations indicate wear on the rubber-metal engine mounts;
  • Leaks from under the crankshaft oil seal and oil pressure sensor occur regularly;
  • With intensive use, they may not withstand the rocker and then the engine is over.
