Disadvantages of the Porsche MCX.ZA engine

- Their appearance greatly accelerates bad fuel, overheating and rare oil changes.
- A lot of trouble is delivered by bursting plastic tubes of the cooling system.
- After 150,000 km of run, you are likely to have to replace the timing chains.
- Weaknesses also include ignition coils, high pressure fuel pumps, turbines and a pump in the tank.
