Hi,
While I hope I'm wrong, I am a little skeptical about there being a permanent fix.
This failure has plagued the M96 engine since it's inception. Porsche is now on a 3rd Gen. replacement Seal and a second set of repair instructions as the first attempts were no real improvement, so we'll see.
That said, of course every Car's Crankcase Seals fail and need replacement at some time in their life, so it will not be the last one if the Car keeps running long enough.
But, hopefully they've cured what has been a premature failure, or at least extended it's usable lifespan...
Happy Motoring!... Jim'99
