Disadvantages of the Opel A22DMH engine
Delphi’s erratic fuel system is the main source of the issue.
Additionally unreliable is the timing chain, which is frequently changed after 150,000 kilometers.
However, you may have the most problems with the version that has a controlled oil pump.
Chips are transported throughout the oil system by such a pump, which frequently jams and drives them.
Additionally, many diesel engines have particulate filter, EGR, and intake manifold contamination.
