When did folks start using the 997 seal?
The raeson I ask is that I am looking at buying a 04 S with 20k miles on her. The RMS was done at 7k in 2007 by the Porsche dealer. Had it inspected and no leaks. Were the dealers using 997 seals in 2007?
Thanks

We've never had a recurring leak when using the 997 seal...
