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.
