Disadvantages of the 6A12TT engine
Maintenance is challenging due to the engine compartment’s extremely dense layout;
Here, hydraulic lifters and an idle speed controller are used for a brief period of time;
Turbines don’t cause any issues, but occasionally the pressure relief valve stem becomes sour; the timing belt can burst the previously set 90,000 km and the valves will bend 100%;
Watch the oil level because a drop in pressure frequently causes the liners to turn.
