Got my fancy pantsy IPR air leak tester in from Accurate diesel. $210 after shipping. Nice high quality build.
Anyway, hooked it up and air is gushing out of the passengers side oil filler tube. Also, air is leaking out of the passenger's side cover at the ccv. So what could be leaking??? The top o-rings on the injector? The oil rail nipple o rings? The o rings on the HPOP???

I took the passengers side valve cover off and hear a leaking gurgling sound but feel no air around the injectors and it isn't any louder at any specific spot. Any ideas? Can I use uv leak detector to look for a mist?

I replaced the standpipe and dummy plugs on the drivers side. Tried the vacuum line and didn't pin point anything. If it was the stc fitting wouldn't it leak back there? Or sound like it was coming from behind the turbo? I'm just gonna redo the injector o rings and on the high pressure oil rail. IDK high pressure oil leaks are about the worst thing in the world.

Ok and I wouldn't hear anything from the back because it would be so loud venting into the crank case and then into the valve covers?
When I test via the icp, with the ipr blocked off , it is noticeably quieter under the valve covers . I'm guessing because less air makes it to the stc fitting?

Commanding the IPR closed with 12 volts or using an IPR plug prevents the shop air from exhausting out the IPR port into the crankcase. Therefore only the STC fitting, branchtubes and oil rails will be pressurized.
The injectors will leak some as the air escapes around the spools and then vents. Not a lot, but some.

I replaced the stc fitting but it had already been updated. Now I'm only getting up to 80 psi?!? Cranked until I killed the bats to get that. The pump didn't seam to sit right when I put it back but looked flat once I torqued it down. I'm getting desperate here. Updated stand pipes dummy plugs both sides and stc fitting. When I had the pump out I put shop air with a rubber nipple to the branch tube and i could barely keep it on there the pressure was so high.
Only thing I can think of now it to try argon to find the leak. I don't really know what else I can do here.

<p>Did you replace the yellow o'ring under the HPOP and the o'ring between the STC fitting and branch tube? With new standpipes, dummy plugs and STC fitting the only other possible leak points are orings on the ball tubes in the high pressure oil rail and the orings in the top of the injectors where the oil rail ball tubes sit and the branch tube itself. How long were you cranking on it after you put it back together?</p>

I replaced the black o ring under the updated stc fitting. Also replaced the yellow o ring under the hpop. I know there are o rings inside the hpop that I have seen fail, yes even in an 05+. Can I test with shop air while the turbo is off and the hpop cover is off?
I cranked the motor for around 30 seconds about 5 to 6 times.
