Disadvantages of the Saab B234E engine

  • This is a reliable engine, and all the described breakdowns happen at high mileage;
  • The main problems here are delivered by the block of balancers and many simply remove it;
  • After lighting up or with a rare change of candles, the ignition cassette often burns;
  • By a run of 250,000 km, the oil pump usually wears out and the timing chain is extended;
  • Very rarely, but there have been cases of unscrewing the connecting rod caps, which is fatal for the engine.
