RMS on US 2003 C2 6spd Cab 34k miles

I am on my 3rd RMS. (2nd IMS is dry) All replaced under warranty

I have a question about these seals. I saw the new (latest greatest updatedest) replacement before they put in yesterday, is it true that Porsche does not put a tension spring around the lip of these seals? Evidently the new Cayenne seal has a spring on the lip.

Does anyone know what the thinking is on that? Is the crankcase pressure supposed to pressurize the lip enough to seal it? What happens when the seal gets older and harder? What happens in the winter when the car is parked facing up hill?

I have not seen the replacement seals, only pictures and it does seem there is no tension spring! Good question! From what I know there is more to the fix than just replacing the seal. The case bolts are supposed to be changed also with ones that come in the kit.
