Is the oil on the dipstick a creamy light brown? As far as the PCV, if it is clogged or stuck, it won't allow air to be drawn from the crank case. As a result, moisture can develope and cause that. However, if the oil is contaminated, it could be that coolant is getting into the engine (bad head gasket, intake leak.)

Head Gasket failure on Ford's 3.8L V6 is, sadly, a common complaint.
