Haha so I'm chuckling that I'm the guy that has said over and over that I'm not afraid of RMS or what not and didn't think the problem was a big deal with the 987. I guess I get to eat my words!
A few weeks back when I was swapping my new wheels on the car and had it jacked up, I noticed the transmission case coated in oil. Over the past few weeks I've noticed some oil spots on the ground too.
So of course, "RMS" came to mind. I took it to the dealership yesterday and they replaced the rear main seal.
My car was built around March or April of 2005. In checking the TSBs I see that they redesigned the seal yet again on May 17th, 2005, so my car still had the older seal.
30,000 miles before I had a leak. We'll see if it happens again. I have an extended warranty so no fear. Really, this seems like a pretty minor problem--not like intermediate shaft failure--but I would expect Porsche to be covering it even outside of warranty and my understanding is that they don't. So yeah, that sucks.
