2001 carrera 4 oil leak
 

I own a 2001 Carrera 4. It is already on its third engine (replaced twice). The problem is an oil leak which destroys the engine. I have 2 questions. The first being is there anyone out there who is having similar problems? Secondy, what has porsche been able to do to resolve the probem (i.e. trade-in for a completely new porsche vs. just replacing the engine over and over again)? I'd appreciate any thoughts.
