What is an IPR , and How do you know if it's broken?

Working on my buddys truck doing some resealing on the motor. Long story short , I was about to unplug the IPR , but realized it was sliding around. The part that has the plug was plugged in , and on the rod that goes into the hpop, but there was nothing behind it. What looks like a washer that the nut goes after was laying in the valley. Is there a repair kit to fix it? Or do we need a whole new one? Kinda emergency so asap help would rock. Let me get a picture of what came off real fast..



The part on the left was on the rod going into the HPOP.
The part on the right was laying in the valley back by the turbo

Hey, I got back to you on your other post, but on the left is the solenoid, on the right is the spacer and there should be a nut that holds it all on tight. Shouldn't be broken at all but may act funny if all that isn't tight.

The nut should be down in the valley too.

To answer you question. The IPR is the "injector pressure regulator" it is what controls the pressure going to the oil rails that feed the injectors.

the nut is probably under the fuel filter canister. I don't know if it is metric or not but I have one in front of me it looks like it is 1/2" fine thread, there is only 1/4" of threads and looks like 5 threads in a quarter inch. the nut you are missing is just a cheap thing stamped out of sheet metal. good luck
