Disadvantages of the 6A12TT engine
- Very dense layout of the engine compartment makes maintenance difficult;
- For a relatively short time, hydraulic lifters and an idle speed controller serve here;
- The timing belt can burst the previously set 90,000 km and the valves will bend 100%;
- Turbines do not cause problems, sometimes the pressure relief valve stem turns sour;
- Keep an eye on the oil level, when the pressure drops, it often turns the liners.
