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.
