If I can just thread a plug where the nipples are that will be a permanant fix. If was major in the way when changing the plugs.

PCV Change '02 Excursion 6.8L
The PCV change is really easy. The non electric heated version.
Don't buy the PCV with the heater hoses as the valve is clipped to the hoses/tube and all you need to do is: Pull the top 3/8' hose from the valve, Pull the valve & tube assy. from the valve cover (leaving the coolant hoses alone) there is enough slack to do this. Use a small screwdriver to pry the clip off. Thus seperating the valve from the tube. Put the new valve in like the old one, reinstall the clip, Put the valve back in cover & reinstall the top vacume hose.
The valve cost me some $4.00 at NAPA and took me a couple minutes to install.
It is located on top of the passenger valve cover. 1-3/8" top hose & 2 smaller 3/16" or so coolant hoses attached to the horseshoe tube at the base.

Has anyone replaced the PCV valve on a 2005, F250, 3V? I purchased the one that was recommended but since through the dealer it is only serviced as a valve cover assy. I do not want to make a mistake replacing it. I looked and could find nothing in the service manual telling how it is done. I do not want to have to purchase the 200+ valve cover....

You should be able to clean out the one you have. Get some carb cleaner and spray through it to get all the gunk out. Air should pass one way and not the other if it is working. It should also rattle. Some of the older engines have a coolant line looped around them and I think the new ones have an electric heater. Niether of these heaters is necessary unless you live where it stays cold for long periods of time.

Did the problem go away
Not yet. I havn't driven it much. But my oil consumption was high as hell. About one uart per thousand.
I will say that the hose between the PCV and the throttle body and the PCV itself were literally dripping oil when I removed them. A large amount of oil.
The new PCV has some resistance to air in one direction. the old one does not. Straigh blow through.
I am leaving on a 300 mile trip to Williamsburg tomorrow and coming back next week. I'll let you know what I find. I am changing the oil within the next hour to get ready for the trip so I will have a good baseline.

Reading through this wasn't clear if anyone found the 2000 V10 PCV. Anyone have pics?
Thx.

If it was a snake, it would have already bitten you.
In reference to a few posts where the users still seem a bit confused about the location of the PCV valve:
^ That illustration shows the valve on earlier models, or a last where the hose connects to the valve. The arrow is pointing to where the hose slips over the nipple on the valve. The rest of the valve pushes straight into a rubber grommet in the valve cover. It should pull straight out, but may require a little twisting/coaxing. Spraying a little bit of silicone lubricant around the valve, while rocking it slighly in the grommet, often helps to make it come out more easily.
Well then maybe I can cap off those lines and eliminate that much extra BS from the engine compartment. Not to mention the possibility of one of those hoses busting or leaking causing problems. I think the newer V10's have an electrically heated PCV valve which sounds like a better solution. Here is one drawing I found in the shop manual but it does not expound at all.
