The trick when driving is to make sure it's fully open so it can't
rattle, otherwise the linkage will shake itself to bits.  And be
careful about rain, because as I said it's in a neutral pressure zone
and stuff can come in as easily as out.

Something is very wrong, then.  Dutiful Passage ('84) had to have the
skylight itself replaced (the OEM ones let you know they're tired by
starting to stink) some time in the early oughts.  But when I last
saw her in ?'07? the original factory gasket was still in good shape
and working fine, along with the original mechanism.
