Can i leave the HPX on, and just use more air/listen to both sides? I don't really have a means of blocking it off tonight

I think it'll push back through the hpop, but I'm not sure. Do you have a way to block one hpo line while pressurizing the other?

The IPR is just gonna leak the air into the block. Can you connect an hpo line from 1 head to the other, then pull one of the rail plugs and apply pressure?

64% IPR is fully closed. But the reading doesn't mean that it's actually fully closed, rather that the truck is commanding it fully closed. Doesn't mean it's actually getting there. Double check that it's installed correctly and functioning. I'd have tried the old one before I would have started some of the other tests. As the previous poster mentioned it's possible to install it so that it can't fully close.

As to lubing up the orings. Lightly oiled, may not be enough. When I did my orings I dipped them all before installing on the injectors and then dipped four full fingers in the oil and slathered it on the injectors like I was putting sun screen on a sexy redhead.

Any time your ramming a cylinder into a tight hole you can't have too much lubrication.

Lolol, i dig your style Joe.

I just felt like the chances of a bad o-ring are much higher than a bad, brand new oem ipr. I also thought i could just take off my hpx and do the air test, which was easy too. Swapping ipr's out later today

1. It matters only in terms of which one reaches where.
2. You have a new HPOP, and it sounds to me like the check valves are not in there - or the oil would have stayed in the system. Since you are rid of the check valves in the HPOP, might I suggest you completely and permanently do away with the HPX. Removing the check valves performs the same function as the HPX, so removing the HPX simplifies the HPO system.

I know it doesn't tell you the size. But I'm pretty sure these are the droids you're looking for. You could probably call Clay and ask, if you're​ in a hurry and need to find them locally.

Taking the HPX off will noty cure your problem. I still have mine on with the T50 witch doesn't have check valves. But doing the Cody test will let you know if the 0-rings are leaking. At this point, I say IPR or loose nut on HPOP. I'd do the IPR first. Then Cody test, if okay check the nut. If you built up over 2K psi with the IPR discounted it should of started. Do you have the wait to start light on?

I believe they're either #4 or #6 ORB. You'd probably save money at a hose shop.
