Disadvantages, breakdowns and problems of the internal combustion engine L86
This is an engine with direct fuel injection and AI-92 gasoline is better not to be poured into it.
The main problem here is the sticking of the hydraulic lifters and the wear of the camshaft.
The cause can be either bad oil or a broken hydraulic lifter cassette.
The forums complain about weak valve springs, sometimes they simply burst
Monitor the condition of the pump and radiators, as the motor is very afraid of overheating
Oil consumption is also regularly encountered due to poor crankcase ventilation.
