The main reason these seals leak is the fact that the crank and the case are not concentric on some 996 engines. The typical story is that - under warranty - several seals are installed and they always keep leaking. At some point Porsche bites the bullet and installs a replacement engine. This is the only solution if you really have non concentric crank / case.

I partially agree. Not ALL seal failures are a result of a bad engine/case. Some are, but not all. Then again, that's why I mentioned BOTH seal cost and MOTOR cost.
I think the RMS issue overall is overblown. Should a buyer be aware of it? yes. Should they run from a car screaming because of something that
may or may not happen to them? no.
Aircooled 911s
can leak oil from about every seal on the motor but no one ever says to throw them out (unless they are a 2.7l Mag/Alum motor
)
