oil leak
#16
This is why they fail: My amateur guess.
I guess the reason it is so hard to fix is the journal diameter upon which the rubber seal's effective sealing depends, is, on these engines: huge. It is about 6 inches in diameter.
The velocity of oil spinning so far from center makes it very hard for the very large seal (that is maybe at the limits of what the rubber material can stand?) to contain all that energy; this might be the reason they fail.
I don't know why the oil seal journal on the Porsche crank is so big. Anybody know?

Here's the strange part: weeks later and I haven't seen anymore drops on the floor. I put a clean piece of newspaper there everytime I park the car after driving it and: no drips anymore!
Can anybody explain this? Ever hear of such a thing? I'm absolutely sure I observed what I describe above.

Drifting
the seal probably expands with higher ambient temperatures and humidity - it could be a seasonal thing.

I started thinking that maybe a tiny piece of gunk wedged itself in the seal for a week or so, produced the leak and then finally blew out or disintegrated.
If that's so, there's no reason alot of other guys, who develop a leak, can't have the same good fortune.
Everything we've said so far is probably gonna turn out to be bogus and I'll have an even larger puddle of oil down there soon.
