Only problem is that Porsche discontinued the old style seal some time ago, so finding one is going to be an issue.
We have seen several DIY PTFE seal installations that were fine, probably because the people that did them took the time to learn about the new seal and what not to do with them. You should never be afraid of something that requires a little understanding and care to complete; the IMS retrofit is a perfect example. Those that take the time and do it right don't seem to have problems; those that don't, well not so much..........
