2003 oil rails

[typ4]

Does no one seal up the end plugs and hex plugs on these things?
I just took mine apart and the o-rings are crispy.
I cant find a source anywhere so measured up for viton orings from the seal source shop.
Thx
Russ

The dummy plugs?

Sounds like the idi valley drain that never gets cleaned out. Should be fine with just matching the o rings.

Russ, I haven't been able to source them either. It's like a non serviceable item.

@typ4 herd same thing but also herd generic Oring kit will work just fine from a 6.0 mechanic (one of the remaining few)

I have been told that the 7.3L ones will work for the end plugs, but I haven't confirmed it for myself yet (seems too easy, but maybe it is true). Part # 4C3Z-6026-CA :

Small oil rail test port plug (allen head on early build and hex head on late build:
Plug by itself is W302297 (old number was W300091), o-ring "base #" is 9C064
Oil rail test port plug o-ring ONLY (2 pack) - 3C3Z-9C064-BA or 3C3Z-9C064-AA (sorry I don't know which one of these o-rings it is, but I think it is the "AA")

It would probably help quite a few folks if you could take an old end plug to a dealership and compare it with part # 4C3Z-6026-CA

Early 6.0, no dummy plugs.
End plugs on oil rails are not service items. One of them had been removed and galled the surface behind the oring groove. Fortunately the threads are ok.
Friend that does these by the hundreds gave me an 06 wavy rail, end plugs are the same.
The little hex plugs are just metric boss orings. That wasn't an issue
The end plug is some kind of quad ring looking seal. And it's an odd size. Not available from Ford or IH.
Oring house had nothing.
AND, as it turns out the Ford reman Injectors with 40k in 5 years on them are complete junk.
Oil exhaust side of the spool just pours oil out on the first three injectors they tested. Picking up new injectors from them Monday morning from Allied which is a pure Power Injector

And the 7 .3 plug things that are in the head are not the same as the 6.0 at all

Would you please post a pic of the end plug that shows the sealing area, and also post the hex head size?

 

[typ4]

socket size is 1-3/8. the later plugs are the same size but are hollow. The early plugs have an insert pressed in that looks to make some sort of mine attenuator in the oil rail. I robbed the seals off the donated ones and its back together. Time to install injectors. fun day

 

[typ4]

So, I installed the new pure power injectors and this truck has NEVER run this good in the 5 years I have been in it. Even the reman ford injectors obviously were crap.
I can say after going thru everything that even a tuner will not cover up bad injectors.
It will actually gett out of its own way in a reasonable time.
And fuel usage is half .

The power will make you not want to sit in a idi again. Lol

Not even. My idi starts within one second of cranking, 3 in the cold weather. These electronic things dont do that.
