The weight of the G4KE engine according to the catalog is 136.3 kg. The G4KE engine number is located at the front, at the junction with the gearbox. The main complaints about the Theta series power units are related to cylinder wear, which occurs due to crumbs from the catalytic converter getting into the combustion chambers. Usually, progressive oil consumption immediately appears, followed by piston knock. Stirring of the bearings. The abrasive formed when scoring occurs spreads throughout the entire oil system and contributes to accelerated wear of both the camshaft lobes and the oil pump gears. And a drop in oil pressure often leads to bearing rotation. Since the end of 2011, bearings with a composite coating have been installed, their lifespan is even shorter. Low chain lifespan. Despite officials' claims that the chain is designed for the entire engine's service life, it often stretches significantly at mileages ranging from 100 to 150 thousand kilometers. The main danger is that the stretched chain often jumps, causing valve bending. Other drawbacks. There are also very weak gaskets and seals here, so lubricant leaks often occur, and the exhaust manifold in the area of the second and third cylinders regularly cracks.
