Disadvantages of the EVA engine
It is not advisable to reduce the lubricant’s quality here because of the extremely small oil channels;
Hydraulic lifters frequently become stuck when inexpensive oils are used;
The valve seats falling out is another known issue with this motor;
The timing resource, which consists of three chains, is roughly 200–250 thousand kilometers; however, the owners’ primary expenses are related to extremely high fuel consumption.
