Disadvantages of the Opel A22DM engine

  • First of all, the CR Delphi fuel system is very demanding on the quality of diesel fuel.
  • The timing chain does not have a long service life; sometimes it is changed at 150,000 km.
  • There are versions with a controlled oil pump and they can cause a lot of trouble.
  • This pump often jams and drives chips, which are then carried throughout the entire system.
  • Problems with the intake manifold, EGR and particulate filter occur in many diesel engines.
