Disadvantages of the Saab B258i engine
- The biggest problem here is grease leaks, especially from under the valve covers.
- Very often, oil gets into the candle wells and there are problems starting the engine.
- Also, through a leaky heat exchanger, oil can seep into antifreeze.
- There are a lot of complaints on the network about a broken timing belt and almost always with a bend in the valves.
- The oil receiver is too low and any sump jam will block it.
