Disadvantages of the EVA engine
- Due to the very narrow oil channels, it is better not to save on the quality of the lubricant here;
- The use of cheap oils often results in sticking of hydraulic lifters;
- Another known problem with this motor is the valve seats falling out;
- The timing resource consisting of three chains is about 200 – 250 thousand kilometers;
- However, the main costs of owners are associated with very high fuel consumption.
