Disadvantages of the B4194T engine
- Despite the forcing, this turbo engine is reliable and has an impressive resource;
- Many complaints are related to oil consumption due to clogged crankcase ventilation;
- Closer to 200,000 km, the main cause of the oil burn is the wear of the turbine shaft;
- The timing belt does not always run the prescribed 90,000 km, and when it breaks, the valves bend;
- The weak points of the engine include the fuel pump, the control unit and a number of sensors.
