Engine Overview and Common Failures
The weight of the 2GR-FSE engine according to the catalog is 179 kg. The engine number 2GR-FSE is located on the cylinder block. The problem with the fifth cylinder. Many owners of such engines have faced scuffing in the fifth cylinder and excessive oil consumption. There are two theories about their occurrence: local overheating due to design defects and a gap in the air filter, through which dust directly enters the combustion chambers. Defective valve springs. Engines manufactured in 2007-2008 were subject to a recall campaign for free replacement of defective valve springs, which could simply rupture due to impurities in the metal. Cracking of camshaft adjusters. The problem with cracking camshaft adjusters during engine start-up affects all GR series units and often only replacing the sprockets helps, but many have to buy new couplings. Other problems. Weak points of this engine also include ignition coils and constantly leaking water pump, and the AFS mixture composition sensors and lambda probes here are very sensitive to poor quality gasoline. Corrosion of fuel pipes and leaks at the cylinder head gasket joints were often encountered in the early years of the engine.
