Disadvantages of the 6G72TT engine
This turbine unit is incredibly dependable and doesn’t cause problems when properly maintained;
The oil burner alone is the subject of numerous complaints, and it will turn the liners if the oil level is not checked;
Another infrequent oil change significantly shortens the lifespan of hydraulic lifters and turbines; throttle and injector contamination is the primary cause of floating speed;
Keep an eye on the coolant level because leaks occur frequently here.
