Disadvantages of the Porsche M96.22 engine
The intermediate shaft bearing is the most well-known issue with these units;
Additionally, these engines require a lot of lubrication, and liner rotation is a common occurrence;
Even after 150,000 kilometers, the timing chain drive frequently needs to be replaced;
A weak pump, reservoir, and cooling system as a whole are among the engine’s weak points;
It’s best to avoid overdoing it on the track because there isn’t a dry sump lubrication system.
