Disadvantages of the TD25 engine
- Due to the fault of the timing gear drive, the power unit is prone to noise and vibration;
- The gears gradually wear out and by 200,000 km the phases begin to go astray in the timing;
- Somewhere on the same mileage, pump leaks appear from the gear block gasket;
- On the electrical side, only the crankshaft position and oil pressure sensor are buggy;
- Detonation due to bad fuel destroys the jumpers between the vortex chambers in the cylinder head.
