Known problem with this engine design. Also afflicts Boxster models.



Please not again the "seal" thing.
There is no problem with "engine design", there was a problem with the manufacturing process and if it happened a couple of times with the new M97 engine (997 Carrera S/4S models), it is just bad luck.



RC I'm sure you heard about the porus bloc problem, several engines were replaced due to this problem (oil in the water)
This was was a problem on the melted bloc process that left some porus inside the bloc, With time, the porus would become bigger and would make a tiny small crak enought to let the oil lubrification system getting in contact with the water cooling system, which lead to oil in water recervoir.

Sorry, English is no my mother linguage but i think you get the general ideia of this problem.
