Disadvantages of the Porsche M96.22 engine

  • The most famous problem of such units is the intermediate shaft bearing;
  • Also, these engines are demanding on lubrication and the rotation of the liners is a frequent phenomenon;
  • The timing chain drive often requires replacement even up to 150,000 km;
  • The weak points of the engine include a weak pump, reservoir and the entire cooling system as a whole;
  • There is no dry sump lubrication system, so it’s better not to overdo it on the track.
