I have to agree with what these guys are saying, if some one replaced your RMS with a new one, they should have some type of garuntee on the work that was done.
On another note, my machanic that replaced mine said that the Porsche uses a CASTING process that is done my a machine that leaves the SURFACE with a ROUGH finish. That is the real cause of the problem. If you have ever seen a casted alluminum block up close, you can see what I am talking about. This is why the seal DOES NOT work properly. In many cases my mechanic would recomend RE-SURFACING, the area where the seals are made to create a BETTER seal between the parts. Porsche is well aware of this because most of the newer models like the 987 from 2005 and up use a newer process that does not leave a rough surface which so far has cured the problem. That's just my 2 cents.
