Though I know the 987 engine is smaller capacity i beleive the bottom end is essntially the same. I had my clutch replaced at 30 k and a small ammount of damp oil was noticed near the RMS. As it turned out it was the intermediate shaft cover seal that had a slight weep. This was replaced and the car put back together. As to the risk of the RMS contaminating the clutch , this is unlikely as the back side of the flywheel is directly in front of the RMS and its shape would prevent oil getting onto the friction surface the other side.
