Engine Overview and Common Failures
The weight of the SR20DET engine according to the catalog is 180 kg. The engine number of the SR20DET is located at the junction of the engine and the gearbox. If you don't skimp on oil, this engine can easily drive over 300 - 350 thousand km. Cheap lubrication clogs the channels, reducing the lifespan, especially the turbo. The timing chain often stretches and starts rattling around 200 - 250 thousand km. The cause of fluctuating RPM should be sought in the idle control valve or the intake manifold runner control valve. Strong vibrations indicate wear of the rubber-metal engine mounts. Leaks from the crankshaft seal and oil pressure sensor are commonly encountered. With intensive use, the rockers may not withstand, and then it's the end for the engine.
