Disadvantages of the Porsche MCX.ZA engine
The most well-known issue with this line of engines is cylinder scuffing.
Their appearance significantly speeds up rare oil changes, overheating, and bad fuel.
The cooling system’s burst plastic tubes cause a lot of problems.
The timing chains will probably need to be replaced after 150,000 kilometers of running.
Turbines, high-pressure fuel pumps, ignition coils, and a tank pump are additional weaknesses.
