E99 f-250 Cant find oil leak driping down back of oil pan?

Hello,

I have been chasing an oil leak for a long time now?? I only have the oil going down the back of the oil pan and it comes down the transmission to the middle of the transmission then drops also very important only leaks at shut off!!! 4 drops every time does not leak while running at all. And does not come out immediately only comes out as it sits so will say in 10 minutes 4-9 drops every time the truck shuts off.

Things I have fixed:

-Tightened the oil pan dipstick nut the giant one that the dipstick goes into the oil pan.
-Turbo pedestal upper and lower O-rings.
-The Exhaust back pressure piston valve that hooks up to exhaust.
-Valve cover gaskets both sides.
-Cleaned and tightened all boots and silicone couplings.
-Made sure the CCV was actually connected into the intake.
-Tightened all oil pan bolts.
-Checked the oil galley plugs I see seeping but no dripping or leaking more like oil splashed on it?

Also I pretty much tightened every bolt I could see not over torqued but made sure they were tight. But here is the other thing I have done. I have cleaned out the valley where there is no oil left at all then there is oil after I start it in the front middle and back of the valley not a lot but enough to see there are puddles in each location and it never over flows it's just there not plugs or sensors are seeping or leaking and what gets me is it is in all 3 locations does the metal pores store oil then it comes out?

So I have come to the conclusion that I'm losing my mind LOL JK do you guys think it could be the rear main seal leak? the turbo leaking but doesn't have major signs when I took it out? or could it be built up oil seeping from boots from the CCV or are there hidden oil lines back there because I'm not sure what to do next I think I just might take transmission off and look but hopefully someone says o ya there is a screw in the back LOL.
Thank You!

dont think a rear main leak, will fill the valley.. Possible, you pinched an oring or 2, when re-installing the turbo?

This is a pic of the hpop. The plug on the back of mine was leaking and my valley was always full of oil until I found it and replaced the o-ring on the plug. If that's your problem don't buy the o-ring kit from ford unless you want to spend $64 on three o-rings. I think you can order them from DieselOrings

Alright I apologize for taking so long to reply I have done a lot of work so far. The leak in the valley was from the HPOP and, I removed it and replaced all o-rings on the HPOP and the fuel bowl from dieselorings.com and since I was in there I changed the IPR and ICP sensor since I just bought the truck a few months ago. The truck runs amazing with new sensors and I now have no oil in the valley well except under the turbo portion. But the leak is only at shut-off and I think that it is coming from the turbo since the galley plugs are not leaking and would assume a rear main seal leak to be much stronger of a leak. Otherwise I will just keep driving and keep inspecting.
Things replaced for oil leak:

Cylinder head bolts were loose causing oil in the valley not the valve cover bolts but the ones near the engine lift mounts located on both sides of motor.
Turbo pedestal and turbo O-rings along with EBPV Exhaust Back Pressure Valve.
Valve cover gaskets and bolts were loose.
HPOP and fuel bowl from dieselorings.com.
ICP and IPR sensor.
