Disadvantages of the Saab B235E engine

  • Engines of this series are disturbed by constant lubrication leaks, and especially at the joints;
  • Hydraulic lifters have a modest resource, they usually knock to 150,000 km;
  • By the same run, the oil pump wears out, which is fraught with turning the liners;
  • By about 200,000 km, oil scraper rings lie and oil consumption appears;
  • Lightweight pistons of this unit do not tolerate tuning and can simply burn out;
  • Another weak point is the block of balancers and is usually disposed of;
  • Also, the ignition cassette, turbine and electric throttle do not last very long here.
