Disadvantages of the Saab B207L engine

  • This is a reliable engine, and its only weak point is the timing chain;
  • By a run of 200,000 km, it is often necessary to change the timing chain and the balance shaft chain;
  • The turbine itself runs well, but its bypass valve fails regularly;
  • Many problems are associated with a short-lived crankcase ventilation valve;
  • Also here they do not differ in resource: ECU, gasoline pump, electric throttle and crankshaft position sensor.
