As i see it, they've done all that they can do, short of a major design change on the engine to either eliminate or reduce the incidence of RMS. On the 987 they reduced the crank weight a bit at the unsupported end to help lessen the "forces"? working on the seal. But in one of the publications testing the new 987S last year, the car was leaking with less than 5K miles on it.
I would think major design changes to this engine to fix the problem would cost a lot in engineering and probably tooling. it's probably less expensive to deal with the individual leaks as they arise and hope the customers aren't too persistent.
One question I haven't heard anyone address is:
if this leak is a symptom of the crank not being ( or staying) concentric with the block, does this indicate an eventual catastrophic failure because of this imbalance? I ask since Porsche does replace some engines after mutilple RMS failures or if it excedes a particular concentric tolerance. If there was no chance of engine failure, why not keep replacing seals? @ $10K a pop for a new engine, you could buy& install a lot of replacement seals.  |

Hi,
No offense, but that's the Best Job of
Whitewashing the issue I have heard to date!
Poor Little Porsche has tried everything and it can't be fixed... 
So the Onus and Financial Burden must be bourne by those who misplaced their Trust and Confidence in Porsche?
Perhaps if Porsche
did actually accept some responsibility, this would ease the impact of the problem somewhat, but they are not and have not!
Those who have received some Dealer/Manufacturer support received it only after shouting themselves Blue in the Face. And this, for the most part, only for those
Original Owners and then with the Car still under Warranty. GOD HELP the Used Car Buyer, because Porsche will not!
Shame on Porsche for not stepping up and FIXING the problem or coming to the Aid of those affected without the requisite Hystronics by the Owner. But, afterall, it's their Nature - they are simply acting like the Multi-National Corporation that they are.
A much greater shame belongs to those Consumers who minimize or downplay the issue. Have we learned Nothing from the Age of Consumerism? We should be shouting this from the Rooftops! Taking every opportunity to cast this Issue and
Porsche in a Negative Light!
This problem is not Miniscule - It does destroy Engines! But, also people's Confidence, Ownership Experiences, and also their Dreams!
We should take every opportunity to criticize Porsche not only for the poor design, but also their Corporate Practices! Owners should write Dealers, the NHTSA, the Federal Trade Commission, Auto Mags and Reviews, Internet Forums, hell, even the World Court if necessary!
Only if our collective voice is
LOUD enough will there ever be a permanent solution to the problem! As this too is the Nature of Multi-National Corporations!...
