I took a few images of this yesterday, but I figured it might be good for the community.
The metal shield over the IPR can lock in place due to corrosion and dirt. My own wouldn't move at first.
In the body of the valve there is a groove machined in and locating tabs stamped into the shield that grips into the groove, keeping the shield in place while allowing it to rotate. It is however a great debris magnet and an opportunity for some corrosion despite being stainless (probably 306).
On a bench I was able to lightly grab it and get it free. Behind the motor, turbo and uppipes it may be more problematic. Perhaps those service mechanics with multiple experience can talk about what they do.
After having it free it was easy to wire brush clean with a brass brush. I'm going to put some anti-seize on mine when it goes back in to try to be proactive in keeping it free.
I can tell ya from first hand experience yesterday, it is a bear to get to on the early side motor. With that said,it still didn't come out and I didn't want to force it and break anything as I had to get the truck up and running for some work being done here at the house. I will pull the intake as it needs the up pipe done. I have that shiney intake that Anthony sent me. I think there is more to this than I am looking forward to.
I don't thing any of the stay wet anti-size stuff would be a good idea do to attracting dirt to it.
Maybe something like a dry graphite coating would help.
It's been a while since I messed with the IPR while the intake was still attached, Jack, but if the plug socket is positioned correctly, why does it matter if you can't reposition it? With an IPR socket and the correct extention, it should just be a matter of pulling the FICM and the plug.
I did this because someone said they couldn’t remove the valve because the connector would not rotate, catching I believe on the cover. So I did a show and tell.
