If you have some milky stuff on the pvc, and are not losing coolant, and drive a lot of short trips in colder climates, this is perfectly normal.
If this is the case, it just means that your oill is not getting warm enough to burn off the excess condensation in the oil, or you need to replace the pvc valve
