Engine Overview and Common Failures
The weight of the SR20DE engine according to the catalog is 160 kg. The SR20DE engine number is located at the junction of the engine and the gearbox. Floating revs. This power unit is quite reliable without any pronounced weak points. On forums, people often complain only about floating revs due to contamination of the PCV system. Sometimes unstable operation can be caused by issues with the throttle position sensor or a burnt lambda probe. Ignition system. Engines of this series are equipped with a distributor ignition system, which lasts a long time. However, it may leak oil from under it, in which case you will have to replace the crankshaft seal. Owners often change the high-voltage wires and it is better to buy original ones. EGR valve. Almost all versions of the engine have an EGR valve with either a vacuum or an electric drive. When it becomes dirty and stuck, the engine loses power and starts to run unstably. Many owners disable it, but this often results in increased fuel consumption. Other disadvantages. Among other drawbacks, it is worth noting regular oil leaks from under the valve cover, low lifespan of the knock sensor, and not the most efficient crankcase ventilation system. On high mileage, oil consumption is often observed due to wear of the piston rings and valve stem seals.
