I have the same problem, when I run the heater. I've kept an eye on all the fluids, and all are good and stay at the same level.

I replace the PCV's in my cars every couple of tune-ups (done every spring), which some would argue is too often. I figure that since it's only about $5, it's not a big deal. Given how easy and inexpensive it is to replace, I would definitely try it first. One very simple test for a PCV is to pull it out when the car is running.
