Hey fellas, yesterday I was changing my valve cover gasket on my 1987 F-150 4.9L 4x4. I had been spraying the EGR nut for the past couple weeks (Where the tube connects to the valve), went to try and break the nut, and what do you know, the tube broke and took the threads of the EGR Valve with it. I went and purchased a new EGR Valve along with some new gaskets for the upper intake and for the new valve. My original plan was to remove the EGR tube where it bolts into the manifold and try to get the nut broken loose on the top in a vice. The more im thinking about it the more I'm thinking I just need a whole new tube. So cracked at the bottom nut (where it connects to exhaust manifold) before I had to leave for work. Had to take off the wheel and only have a small window to mess with it at. The nut would spin but it clearly wasn't backed off. I'm guessing this is some sort of cross threaded double threaded bolt. So tomorrow after work ill try to break loose the actual bolt rather than getting the nut to spin.

Any guidance with this or recommendations would be greatly appreciated. Do you guys think the old tube is salvageable? Any special way to get the bottom part of the tube off? Truck is pretty rusty but all the bolts are in good shape.

Thanks fellas Ill attach some pictures of what I'm working with in the morning.

 

This is where the tube broke from the EGR valve. Is this salvageable?

Best I could do before work was this picture of the nut connected to the manifold. On mine the size of this nut and the bolt in the middle is about 1 1/4, haven’t tried any metrics so don’t know for sure.
