I recommend using the oem Porsche seal for the flywheel seal. I used the other one (a few bucks cheaper) and had immediate leaks. I replaced it with the oem and the engine is now dry.

By the way, to get the old one out, use a punch - insert the end into the notch at the rear of the engine (the top of the seal) and give the old seal a good whack. It will deform the seal enough that you can easily get it the rest of the way out with a screwdriver
