I know not a ranger, but I have a f250 6.0 ipr problem

Ok well here it is, I have a 2005 f250 power stroke 6.0, and I am trying to remove the IPR valve. And I have bought the socket, everything for it and it is not moving much at all. I will attempt to post pictures of what is going on. My ratchets and breaker bar is getting caught on a little tab. I have tried everything I can come up with. What am I missing?
I am having trouble putting up the picture.

Well I got that thing out finally, the special socket was catching on something.
