Keep in mind that the oil is cold and will take it's own sweet time to blow it out.
This is the basic design idea of the early pumps. The pump in the 6.0L are fixed displacement.
Mark after seeing this I am not the only one leaking at that rear port on the oil cooler now.
I almost am willing to bet that the PO reused the gaskets when he did the delete on mine.
So I will be doing a R&R with all new gaskets. I am so tired of that stupid delete hose I am
ready to put a cooler back in from BPD and call that good.

Nice post Sean! Hadn't seen that video before.
Lots of areas to get frustrated w/ these 6 liters lol (but I still like them)! I am tired of the failing thermostat train. Finally broke down and ordered an International one.

Good morning gentleman. I am up early this morning I have found a friend of mine last night that has the valve I have to drive about 20 miles to get it. I'll be leaving out of here within about 20 minutes and get back and I'm going to make me up at hose system. And we're going to check it out and see where the air is coming from. I do appreciate it very much, the help on this. y'all have a great day I will check in later when I get some results.

If you don't mind my asking. How much did you have to pay for it?
The funny thing about the swash plate pump is they could of put a small servo in the pump and they could of gotten rid of the IPR. But
that adds complexity in a different form.
Also had they done that then they could of done my other complication adding idea. The injector HPOP system should of been 100% isolated
from the engine oil system. That way they could of used an oil that is less prone to causing stiction. That may even not of been an issue if
the dirty engine oil was not getting to the spool valves. But then you would have two oil systems to change and other things like a scavenge pump
to pick up the oil at the injectors once the injector dumps it into the oil exhaust ports. That in turn would add more plumbing.
I think with all of that added up we could have a $30,000 engine.

Sean - I paid $84 for it. Crazy how the price has gone up.
Visurveyor - below is a link to another forum where a member discusses the early 6.0L (swash-plate design) failure points.
Update; Ford 6.0 hpop fix (continued)

I'm back gentlemen. Question does the noise coming back up through the oil filter sound like bubbling oil. If so how do I determine which injector is bad if that's what it is?

It is also blowing oil back through the air hose to the fitting in like little pulses I unplugged it and oil blew out from right there where it was plugged in .what does that mean

Your putting pressure into a closed vessel and I would expect it to blow back at you when you disconnect it.
If there was a large leak then you would not get so much, But with a small leak it will.
As for finding a leaking injector you will have to leave pressure on it until the oil is all blow out up to the point of any leak.
As I said last night cold oil will not move very fast at all. You may have to leave it on a quite a while. You may want to add
a shutoff valve to your hose so you can trap the pressure in the system so you can unhook your air hose and let it sit.
That way it does not spray back at you

Well it's pouring down rain here in Jacksonville Florida. So I'm going to a little bit of a break. I left the air plugged in thinking the same thing we're it don't blow back and I'll see but I'm definitely getting a lot of bubbly bubbly gurgle gurgle out of the bottom of the oil filter housing so we'll see what happens

I think i might need to clarify what i hear. It sounds like oil with air being blown through it like when we were kids with a milkshake. I don't hear no clear air coming from anywhere in filter housing or on my to fuel rails right now. I'm getting a small click click driver side rear injector i think. Maybe that information will help a little bit thanks guys.

Thanks Sean much appreciated. I'm sure Mark will probably take a look at it later on. I'm still looking around checking this and that but have to make a decision

I don't think you will hear a bubbling sound from a leaking injector. You will hear an injector leak with the valve cover off and listening carefully - might even need a type of stethoscope, or even just a section of hose. Sean is correct - the oil needs to be pushed out to hear the air leakage sound.
The bubbling sound does sound like something leaking on the suction side of the HPOP.
Is the oil filter out and the filter cap removed? That is how you listen at that point - a stethoscope can sometimes help there also (listening at the bottom).
