Disadvantages of the Alfa Romeo 939B1000 engine
- For a turbo engine of this power, this engine is very reliable and has no particular problems;
- Since there is direct fuel injection, soot on the valves forms quite quickly;
- The engine requires special oil or the turbine and hydraulic lifters do not last long;
- The timing belt is recommended to be changed every 60,000 km, or if it breaks, the valves will bend;
- With intensive use, lubricant consumption appears up to a liter per 1000 km.
