Disadvantages of the Alfa Romeo 939B1000 engine
This engine is highly dependable and has no special issues for a turbo engine of this power;
Soot on the valves develops rapidly due to direct fuel injection;
The timing belt should be changed every 60,000 kilometers or the valves will bend; the engine needs special oil or the turbine and hydraulic lifters won’t last long; and with heavy use, lubricant consumption can reach a liter per 1000 kilometers.
