I have to agree, some cars leaked no matter how often they were driven. Here is the offical response from Porsche regarding RMS leaks. And I know of a new 2010 GT3 that is leaking in the dealer showroom so I don't think the problem is fully addressed with the new cars. The reason for the leaks is the seal is held by a vacuum which apparently weakens when the cars are not used often, the vacuum weakens and oil seeps. I would imagine that there is a better than 50% chance that the RMS will leak on the new RS. My 2008 RS has not leaked so far "knock on wood".
I received this letter today from Porsche Cars North America, Inc. in response to my email:
Dear Mr. Greco
We are in receipt of your inquiry addressed to Porsche Cars North America. As the person in charge of customer
satisfaction in your area, I am responding to your request. I would like to address concerns you raised regarding the oil
seepage issue on your 2008 Porsche 911 GT3RS.
Please be advised that GT3 engines have a design which is unique from other 911's because of it's exposure to very high
RPM's. The rear main seal of these engines is held tight by a vacuum created inside the engine block. If the vehicle is not
used for prolonged periods of time this vacuum pressure may decrease allowing a small amount of oil to seep past the
seal. Due to this special design, oil seepage can occur in GT3 vehicles that are not driven on a regular basis.
Your warranty manual indicates that your responsibility for normal vehicle use is for your vehicle to be driven daily over
a distance of several miles. Your vehicle was designed with the assumption that it would be used within these guidelines.
If it is not, you may experience some oil seepage; however, this is not a defect in the vehicle but simply a result of lack of
use.
Thank you for allowing us this opportunity to explain.
Very truly yours,

Dearlers told me on the earlier model 07 GT3 have 2 common factory faults..
1) starter (difficult to start the engine; sounds it had a flat battery when start)
2) RMS oil leak.
probelm 1) should be solved on the new model (like your 2011)
not sure abt 2)

The letter is corporate dribble from some admin assistant, if the seal is not a defect
then how do they explain the 100's of RMS that were repaired under warranty or several buy backs of cars with recurring leaks.

I have an '08 RS 3,400 mile garage queen (not by choice, personal issues beyond my control, really 
) and zero RMS leak! It has "Puff the Magic Dragon" as start up and LSFW rattle....the "normal" stuff but no oil. I feel a bit left out, now if I never have a "catastrophic coolant loss" I'm certainly the red headed step child.

You know if you let it idle for a few seconds before turning off will cure the smoke issue. It seem that all the GT1 block engine does this. My 996T did the same thing. I think it'd due to the dry sump.
