On the steam from the tailpipe, for those in California disregard this. The
mandated of oxygenating the fuel is still in effect and will cause this type
of steam come from the exhaust along with small puddle of water drips.

Some folks have already replied about the oil fill tube; hopefully
that is the cause as that should be rather benign. How does the oil
itself look? Is it just a foam on top of the oil or is the oil
itself discolored as well? If you have enough water getting into
the oil, when you drain it out it will look like chocolate milk.
This is usually a result of antifreeze leaking into the oil,
the most common causes of which are a blown head gasket,
warped/cracked head, a cracked block or a failure of an intake
manifold gasket. In such a case, you may also notice white smoke/steam
coming from the exhaust even after the engine is warmed up. If you
smell the exhaust it will smell like antifreeze or have a slight
sweet smell to it.
If the oil itself looks fine and you are not losing coolant then
you are probably OK. You might want to double check to make sure
you aren't overfilling the oil; if the oil gets up into the crank
it can get whipped up into a foam.
