I'm not sure how you keep missing this, but where does
the air comre from to "aerate" the oil in a remote
reservoir shock?  You just acknowledged that it is
sealed and contains no gas in the oil-filled area.

Not at the pressures and temperatures found in the
shock, no.  The whole point of the reservoir is
keeping the oil cool.  Gas-charged shocks without a
reservoir can experinece boiling under very heavy use,
but that's not "aeration".

No.  Crankcases are never sealed.

Bummer.  You should have stuck to the subject at hand,
then.

That was the whole point of your post.  I think you're
confused about the term "aeration".
