Disadvantages of the Saab B235R engine
- First of all, this motor is worried about regular oil leaks, especially at the joints;
- Hydraulic lifters have a modest resource and often begin to knock to 150,000 km;
- By the same run, the oil pump often wears out, which is dangerous for liners;
- Closer to 200,000 km, oil scraper rings lie here and lubricant consumption appears;
- This unit does not tolerate tuning, its lightweight pistons can simply burn out;
- The block of balancers does not differ in a large resource, usually they get rid of it;
- The weak points of the engine also include the ignition cassette, turbine and electric throttle.
