sepsis311,
Because of the air/oil cooling of our cars, the fan belt is a critical part of the survival of the engine. (By the way, "druck" refers to the oil pressure on your car, which I suspect is a grey market import, originally sold in Germany.) The vast amount of oil in the dry-sump system helps to remove heat from the heads and crankcase, but the cylinders rely upon moving air, which is provided by the fan (which has your alternator mounted behind it).
The guys here are concerned, because by the time someone gets to the ownership stage in these cars, they usually have the critical nature of the fan belt etched in their brain. The drill is: Alternator light comes on: STOP. Shut down, open the engine lid and replace the belt with the spare you carry for emergencies.
I suspect the heat build-up in your pistons and cylinders have resulted in scoring of both, as the overheating in the cylinder walls thins out the oil to the point where its lubrication properties are reduced. This could be expensive.
Guys: Might the high oil pressure showing be caused from deposits congealing in the galleries under greater heat? I would have expected the oil to thin and the pressure to drop.
Let us know how bad things are.
