Engine Overview and Common Failures

This is an engine with direct fuel injection and it is better not to fill it with gasoline AI-92. The main problem here is the sticking of hydraulic compensators and wear of the camshaft. The cause can be both poor oil and a failure of the hydraulic compensator cassette. In forums, people complain about weak valve springs, sometimes they simply break. Keep an eye on the condition of the pump and radiators, as the engine is very sensitive to overheating. Also, oil consumption is regularly encountered due to poor crankcase ventilation.
