Perfectly normal.

More pronounced in winter, and when more humid out. It is a combination
of condensation from inside the crankcase and cylinders as well as a
byproduct of combustion. It isn't "water" in the true sense though.

It is a mixture of water, Sulfuric Acid, Hydrochloric Acid, and a host
of other nasties. This mixture is what rusts out your muffler/tailpipe
when you take short trips that are not sufficient to heat/dry out the
exhaust system.

I noticed a strange thing this weekend.  When I first fire up my van I
see condensation coming from the tailpipe, both as steam and small
droplets.  The condensation does not smell like coolant.  After about 5
minutes or so, the condensation goes away and the exhaust fumes are bone
dry.

What gives?  I thought the obvious, that I may have a blown head gasket,
but I don't seem to have any of the other indicators (i.e., sounds,
engine running hot, coolant overflow, etc.)
