What did you do with/to your Boxster today?

The black crud? It's definitely not oily or greasy, just dry dust (clutch material?). This clutch was completely toast and that dust was all over on the drivers side.
I'll take a closer look to be sure. Axle boots are not split or deteriorated.

Yeah that inside shaft cover being oily is what I noticed. Look at the cover on that side of the trans. I'll bet it is oily behind the output shaft.

Link to my thread and pic of the seal along with a Transmission Service manual in PDF.

PS Hadn't even considered that the clutch friction material sticking to the gear oil might be the reason the seal went out, but zooming in it does appear to have the black dust in the seal.....

Here is a pic of my axle. Before I changed the seal.
Also could you post a pic of your original clutch disk for comparison to the new "upgraded" clutch disk? It appears the new disk has quite a bit more friction material than the original disk. Might have to consider the additional rotating mass when I change mine.

Mine looked just like that and I could smell the gear oil burning on the exhaust. It would be real easy to change that trans output shaft seal before you put everything back together. Of course it can also be done later.

Good eye. It was a very light misting from a bad output shaft seal combined with possibly clutch disc material (that stuff was everywhere) or just standard engine/road gunk.

It was all the way down into the rivets. I'm sure it was original to the car. It measures exactly 5mm overall.
