What you have is probably nothing more than a build up of condensation in the
crankcase, caused primarily by the short drives to work
When the engine is not allowed to rise to operating temperature and remain
there for a reasonalble time, the water vapor in the cold crankcase air
condenses out into the oil. And because the engine/oil doesn't get hot
enought, the condensation remains, instead of being turned to steam and
vented to atmosphere as it would normally.
The quickest solution is to warm the car up, drive it for 30-45 minutes,
preferebly on the road (stop and start traffic will just aggrevate the
problem). Then, once back home, to a thorough oil/filter change, while the
engine is still warm.
To avoid the problem in the future, make it a point to drive the car for a
reasonable period of time every so often, like on the week-ends if the 4 mile
work comute is all that's possible during the week. This will help vaporize
the water in the crankcase and allow it to escape into the air.
I had the same problem a while back due to a short work commute, and since
then, no more problem. Besides, it's a darn good excuse to go for a long
ride!!
