Disadvantages of the Saab B234i engine
This family’s power units are all incredibly dependable and particularly atmospheric.
Balance shafts are the primary cause of most issues, and many people just remove them.
The engine’s timing chain frequently stretches and begins to rattle loudly after 250,000 kilometers.
Leaks from collapsed pipes and hoses are a major source of problems here.
The oil pump, short-lived wiring, and mass air flow sensor are additional engine weaknesses.
