Anyone else tried this? "The GT3 Motorsport seal (not a Porsche standard part) is the same bore size as the 996/997 seal but has two protective flanges at the rear. If fitted in reverse the inner flange forces itself to flip backwards and touch the outer flange which is already forced onto the crank with a spring. This prevents any oil from possibly leaking even if the bore is out of tolerance."
