How did you check the HPO oil line orings/fittings? Both ends of both lines?
If it is only showing up when warmed up, use a shop towel and wipe down the HPO lines. See if either of them are oily, or have rough spots.
If the coating is damaged (ie from rubbing), they can start to leak through the line and can easily burst and risk of fire. Be sure to check carefully

Not sure if you've ever read Jesser02ex "oil in the valley" how to but it is the 2nd post in the thread below.
Suggest you clean valley and then stuff enough clean paper towels in there to hold them in place. drive around then look and see were it's leaking

1. Do you have HPx? Make sure the fittings aren't leaking
2. HPOP gasket between the pump and the reservoir
3. HPOP Hoses (2x) and their fittings have orings
4. HPOP fittings on HPOP (2x) and their threads can leak if they've been disturbed or replaced without proper clean/dry/loctite procedure
5. HPOP lines (2x) themselves can have a leak in the hose from a rub or age
6. ICP on the drivers side head can leak at the sensor threads or electrical connector if failed
7. IPR if it has been removed. I suppose it can leak through if it failed completely, but I haven't read about it leaking oil through the sensor.
Are you SURE it isn't diesel fuel? Have you rebuilt your fuel bowl?
Tip: I use a piece of stiff wire with the end coiled and cut into a point. I can stick it down through all the hoses and wires into a rag and give it a few twists to snag it well and pull it up through the nest of things I use a long screwdriver to reach down and push it into the nooks and crannies of the valley to soak up oil or whatever.
Hope this helps!

The oring was pinched completely around like half went in the hole and half squeezed out.
So I need a new oring, anyone know what size it is?

well, not sure if I found "the" leak finally, but I found A leak, and its a doozy. After reaching operating temperature, the truck would puff large clouds of blue smoke upon stopping. Long story short, the internal turbo seals are shot.In fact, the seal ring on the turbine side is completely missing. Also found some fibrous material similar to brillo pad packed in one of the oil passages. Both the compressor wheel and the turbine wheel have been touching their housings. The oil blowing through the turbo was hitting the EBPV flapper and running down the shaft and onto the actuator arm.
So since I have to go all the way through it, I got the EBPV delete pedestal, EBPV delete rear housing, upgraded 66mm compressor and housing, replacement turbine and shaft, replacement, bearing housing, and new internals. I am not going to do a CCV delete, but I am going to replace the stock one with something I will work up so it doesn't have the large hump restricting airflow. After I get everything cleaned and assembled, thinking oil change before running it.
Anyone have any thoughts or something I might be missing? I am about $900 into new parts so far, and I don't want to mess anything up.
