Thank you guys for the help. I got everything cleaned up and narrowed the leak to the front. I then additionally cleaned that area more. After some advise from Jason...a big thank you...I ruled out the back plate on the HPOP by cleaning better with some carb cleaner. So the culprit is the o-ring pushing out in the fitting that goes into the HPOP that is closer to the cab. Good news is it can be somewhat easily fixed and am looking forward to getting this progressively worsening oil leak fixed as it's been this way for a long time. Bad thing is this is on an Excursion and the mounting plate for the glow plug module may have to come off...no biggie as I need to replace that module and subsequent plug pigtails anyways. I am going to go ahead and replace both lines...though the other 3 connections aren't leaking...with the better jic units.

There's easily 15 different O-rings just in the valley alone, when you begin rummaging around in there, you're gonna find new leaks, it's a thing, Just sayin...……..
