After weeks of waiting to get a .80 mm flywheel shim I found, that while I could get it over the crank to test the endplay, it did not turn freely on the crank. Not good.
After lots of measuring that led to no obvious issue, I sourced a shim from another vendor just to see. Voila! It was the shim itself.
After quite a bit more time trying to determine why, I noticed I could feel spot that wasn’t smooth on the interior. A photo with enlargement revealed a bur on the shim. So much for quality control, on a Porsche original part no less.
I guess the lesson is always inspect your parts. Even if they’re from the ultimate vendor.
