Disadvantages of the QJBB/QJBA engine
- Most engine problems are somehow related to the Delphi fuel system;
- From impurities in diesel fuel, the pump shaft wears out and its chips clog the nozzles;
- The double-row timing chain only looks menacing, but it itself stretches to 150,000 km;
- The upper heads of the connecting rods are broken for 200,000 km and a characteristic knock appears;
- On specialized forums they often write about failures of the vacuum pump and generator.
