Help diagnosing hpop leak
I just replaced my hpop lines to CNC fabrication hpop lines because it look like my SCT fittings where leaking on the hpop. There doesn't appear to be any leaks coming from the lines but now it looks like there might be a leak underneath the hpop. I let the truck set for about 6 hours today and the oil level in the hpop was still at about three-quarters full. I have tried to clean everything the best I can but can't seem to figure out where the leak is coming from. Cleaned out the first two dips in the valley and ran the truck for a couple of miles and I had a little bit of oil in both dips of the valley. I felt up underneath the IPR and there was some oil but not sure if it was residual from changing out the hpop lines. Any suggestions on how to diagnose which part of the hpop is leaking? Should I just change out the IPR and go from there? The tin nut on the end of the IPR feels like it is tight. The truck seems to run fine and my ICP is right around 560 at idle and I have 11.4% duty cycle. Not sure what to do from here, hoping I don't have to take out the hpop and reseal everything. Any suggestions would be greatly appreciated, thanks

Isn't the location you are describing roughly where the "non-servicable" plug is at? If so, I believe that takes removing the HPOP to fix.
I could be completely wrong on both if those, but when you ask for free advice sometimes you get what you paid for.

that's a great pic sous! I'm thinking it's either the ipr port or non removable plug. The hpop is one of the things I haven't had to do anything to and dont know that much about other than some research. Apparently there is quite a few places on these that can develop leaks. It is very hard to see down under the pump and difficult to decipher which location is leaking. I wasn't sure if most just pulled the hpop and R&R the whole thing. I thought about just going ahead and trying a new IPR being that I'm pretty sure that both of my trucks have the original IPR and wouldn't hurt to have one ready to go when they fail. They are pretty expensive though
