'91 200Q: Oil "sweating" around crankcase breather hose connector

[Arun Rao <rao@pixar.com>]

Anyone else seen this?  I was poking around under the hood, when I saw
that there's some oil in the area where the crankcase breather hose
connects to the block. (At least that's what I think it is: driver side,
toward the firewall, pretty far down on the block but easily visible).
It isn't very much, and I've noticed no drips or inordinate oil usage,
but I thought I'd better be safe than sorry.

Any pointers appreciated!
