The 2.5-liter turbo Volvo B5254T engine was assembled at the company’s plant from 1995 to 1999 and installed on a number of popular models of the group of that time, such as the C70, S70 and V70. After modernization in 1999, such a power unit received a slightly different B5244T index.

Disadvantages of the B5254T engine
- This motor does not have a phase regulator or electric choke and therefore is very reliable;
- In specialized forums, the oil burner is most often discussed due to contamination of the crankcase ventilation;
- After 200 thousand km, the cause of oil consumption is usually turbine shaft wear;
- According to the regulations, the timing belt is changed every 90,000 km, and when it breaks, the valves always bend;
- Also, the engine mounts, pump, thermostat and fuel pump do not last very long.
What do you mean by engine lifespan ~280000 km? I have 329000 and the engine is still running.
