Ipr is under the turbo, on the hpop housing, sticking out towards the driver side. Remove ficm , rear valve cover bolt, and cac tube, or from the bottom, remove the heat shield and have a long extension or arms that are skinny. Its a pain in the ***. 1 1/4 or 1 3/8 socket I believe. Rails are under the valve covers, and STC fitting is under the turbo and under the hpop cover. You are going to have a hard time diagnosing this without the correct tools, or a scanner that can see ipr and icp pressures or percentages. To pinpoint hpop leaks you need some blockoff tools for the hpop rails, and a fitting to pressurize the system with shop air. Buy the ipr at an International big truck shop. Its $145 instead of $250 from ford. Where are you located?

There is an International Dealership on the NorthWest side of town (on I-37) in CC. FleetPride 361 289-5151. They need the International Part #.
It could be the harness and not the IPR itself.
If you have metal or debris on the screen or if the screen is damaged, you probably have other problems also.

Check....
Look at the connector for damage, or a wire pulled back in the plug. Look close. If you can get the ipr out easily, you will know very fast if it is damaged. Check the oring and the screen on the end. You may find the screen or the plastic broken from debris hitting it. If this is the case you can try cranking it over with the ipr removed. It will make a mess, but it can blow some crap out of the ipr hole. You WILL get oil all over the ground. Lay a rag over the ipr hole when you try this to catch some oil. And this is not the correct way of fixing this problem, but I had to do this once, and that truck is still on the road daily with about 12000 miles since the problem. Good Luck

ok thanks again for all the replys, so i changed the STC connector and the only leak hear is coming from the HPOP shaft and according to the troubleshooting steps thats normal...and the screen on the IPR valve is pushed n kinda crushed and with a little tear in it...so does this mean i need a new IPR?
