Disadvantages of the B5234T engine
This is a very clever turbo engine that can travel up to 300,000 kilometers with the right maintenance;
High oil consumption is frequently caused by clogged crankcase ventilation;
The turbine shaft may wear out closer to 200,000 kilometers, which is also prone to oil burn;
The unit’s weak points are the upper support, thermostat, pump, and fuel pump. The timing belt does not always serve the planned 120,000 km, and when it breaks, the valves bend.
