- Hydraulic lifters have a modest resource, they usually knock to 150,000 km;
- By the same run, the oil pump wears out, which is fraught with turning the liners;
- By about 200,000 km, oil scraper rings lie and oil consumption appears;
- Lightweight pistons of this unit do not tolerate tuning and can simply burn out;
- Another weak point is the block of balancers and is usually disposed of;
- Also, the ignition cassette, turbine and electric throttle do not last very long here.
