https://www.ford-trucks.com/forums/9...-question.html Here is a link to a thread that may help. You will also get better response if you post any questions you have on that Power Stroke page.
Good luck.

Lightbulb Give some more info

Is this a liquid oil stream or a slow leak?
Where is the leak exactly?
Turbo area? Engine vally?
etc...

Here is some added info to help you
From the manual
Overview
The High Pressure Oil Control system consists of the high-pressure oil reservoir, highpressure oil pump, injection control pressure regulator, Injection Control Pressure (ICP)sensor, high-pressure hoses, and oil rails in the cylinder heads.
The High Pressure Oil Control system is used to actuate the HEUI fuel injectors. The PCM controls an electronic pressure regulator to regulate oil pressure to the injectors. The high-pressure oil flow within the fuel injectors is controlled by a solenoid located on top of the injectors. Oil pressure supplies the force needed to pressurize the fuel in the
injector to initiate fuel injection. High Pressure Oil Control Subsystem
Description & Operation The lubrication system is comprised of a low-pressure system and a high-pressure system.
The low-pressure system provides primary engine lubrication while the highpressure system provides the hydraulic pressure required to actuate the fuel injectors.
The low-pressure lubricating system draws oil from the engine oil pan through the oil pump screen cover and tube into the oil inlet passage in the front cover. The Gerotor oil pump pumps the oil back out through the outlet passage in the front cover. One oil path sends oil flow to the high-pressure pump reservoir initial fill gallery (integral to the cylinder block) and through the anti-drainback check ball. During cold start the oil feeds in two directions from the anti-drainback check ball. One feed leaves the check ball and enters the front cover. From there it enters the high-pressure oil reservoir. The second feed exits the check ball and enters the left bank valve lifter oil gallery. Pressurized oil that enters the turbocharger assembly lubricates the compressor/turbine shaft. The oil drains back through the turbocharger mounting pedestal and back into the oil pan. The valve lifter oil gallery supplies pressurized oil to the valve tappets and to the piston cooling oil jets. Oil from the valve tappets is routed upward to the cylinder head
valve train through hollow push rods. Oil drains back to the oil pan through return ports. High Pressure Oil System Explanation
During initial start or cold start, the high-pressure oil pump receives unfiltered oil from the left side valve lifter oil gallery through the anti-drain back check ball valve. Once the engine starts or during warm engine starts, the check ball closes and the high-pressure oil pump receives filtered oil from the high-pressure oil pump reservoir.
The high-pressure oil pump pumps the oil under extremely high pressures (4,115-20,577 kPa [600-3,000 psi]) through the left and right side high-pressure supply hoses to the high-pressure oil rails (integral to the cylinder heads). Once in the oil rail, oil is fed to the fuel injector bores through oil feed galleries (4) drilled and machined in the cylinder
head. The high-pressure oil then actuates the fuel injectors.

welcome to FTE but not to sound like a jerk but... dont post the same durn question 2 times with out saying were the leak is specidfically coming from, how fast its leaking when i leaks, pictures would help. theres plenty of spots for this big ol pig to leak and you need to be SPECIFIC lol

a common spot is the back of the turbo pedistal, the orings fail and leak down the back of the block leaving a nice spot in your driveway. another spot is either the pump its self or the lines, which would let oil pool on the top of the motor. give some detail and guarentee we can solve the issue.

If it is leaking oil a lot, I'm talking a gallon in 100 miles a lot, then it is most likely the oil galley plugs on the back of the block. There are new plugs from Ford that have a different o-ring on them than the ones that came factory.

Got a part number for that? I know mine is leaking seems to be worse now that I have synthetic in it.

There are two high pressure oil plugs on the front & rear of each head.
They will start leaking for no apparent reason, it seems to be a rather common problem.
This is the p/n for the new style plug:
4c3z-6026-ca

Have a pic of the plug, but I am unable to post it. Will e-mail it if you want.

Thanks. Do you know if it is that much of a PITA to switch them out?

Nope

I would think that two of them could be a real pita. I have not done mine yet. Scatgo
how about you doing yours and then build a guide on the how to and post for a everyone else to use.

Just kidding, someone on here has had to have done this aready. Perhaps Jim has.

Reach behind the fuel bowl and grab the shield and pull it off of the fuel pump. Check the hoses there for leaks. If no leaks to the right of the fuel bowl there a a fuel filter pressure sensor, made of black plastic and metal. It can leak. When you find the leak post back for more help. I hope its not the btm of your fuel bowl but if it is we can help you jimmy that too.

It may help to wipe everything clean first.
