Disadvantages of the Saab B308E engine
- This is a very reliable engine and its main problems are associated with lubrication leaks.
- Especially often, oil crawls out from under the valve covers and fills the candle wells.
- Also, grease can seep into the coolant through the heat exchanger.
- The turbine is not the highest resource, sometimes it runs less than 100,000 km.
- Monitor the condition of the timing belt, its resource is small, and when it breaks, the valves bend.
