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.
