Disadvantages of the Porsche M48.70 engine
Although they are less frequent than their predecessor, seizures in the cylinders do happen;
This engine’s intake shafts’ faulty phase regulators are another issue;
Expansion tanks and coolant pipes frequently burst and leak;
The fuel pump in the tank and the injection pump of the direct injection system cause a lot of problems; a low resource for this engine distinguishes turbines, ignition coils, and a thermostat.
