There could be a chance of it if it were stuck open and allowing you to burn your oil thats getting forced through it into your intake. When its only $1.69 to replace it with a new one at the parts store, I'd just replace it if there's any doubt.

There's a metered ammount of air that bleeds through the PCV valve. If it's plugged, you lose that ammount of air and will cause a slightly rich condition at idle and your hydrocarbons will be up. As Ben says, for a couple of bucks, it's worth keeping one in the glove box. It's actually one of the first things checked when the technician gets a slightly high hydrocarbon reading.

Now, where do I purchase a new one?
Every parts store I've been to, shows, "No Listing" for 2003 Ranger 4.0 sohc PCV valve.
Is it a 'Dealer' only item?
