I think I've got one in my glove box I'll check Friday when I get back to my truck. There's a good chance that's what it is. If the ipr is starting to go it'll just puke out oil somehow for some reason. That's what mine did when it went. If I have one you can borrow it or just put it on your truck and replace mine. Up to you. I have to go down that way so if it's there I can meet you or drop it off somewhere. When I leave there I'm heading through Exeter and tunkhannock so I can drop it there somewhere too. Pm me if you're interested. It may also be the electrical solenoid portion of the ipr and not the actual valve going bad. Also that's what my issue was. That's why I'm not sure if I have the whole ipr or just the valve pieces in the glovebox.
