Anyone tried this?
So I used a port a power to pressure up my oil rails and here's my results. I'm looking for someone who has done this to compare notes and knowledge. Cause I ain't got a clue what I'm looking at!!

Actually Keith Stone, the joke is back on me. I saw 3 posts and they all looked the same (I was not able to view them at the time) and thought he triple posted.
That is what I get for ASSuMEing, lol (I thought he was stuck on a big lake somewhere with a bad dial up connection). Sorry buddy.

No prob. I can take criticism pretty good. Lol! But no one has tried this? Jim rosewood was the one who suggested it. Just thought someone would have something to compare to. If any of y'all know Jim personally could you turn him onto this thread? Thanks!!

You need to replace your injector O rings , The pressure should stay at or around 2500-3000 psi without fading so fast .If you pull the valve covers , you will see or hear the leaks ...

David!
You didn't leave a phone number, I have no way to reach you.
Sorry, I'll be out most of today.
Those videos look 100% fine to me.
3000 psi is a LOT of pressure and if there was an issue it would drop fast, or you would nto be able to build pressure at all.
To me, looks as if the heads hold pressure fine.
Did you do that to the HPOP too?
Usually you want a check valve in the supply line between the pump and gauge, but the port-a-power might have that internally.
Edit: There really is nothing stopping the high pressure oil internally as in no seals or antyhing other than a really tight fitting Poppet Valve and it will NOT hold 3000 psi indefinitely. 3000 is a lot of pressure and it WILL drop just as shown with any good injector.
A shows where the HPOil enters the Poppet Valve area, B shows where the oil will leak out.
If you pull the valve cover and remove a Solenoid (4 screws) from an injector on the side you are testing you should see oil coming out the top of the injector under the Armature Plate (small 1" square plate).

Easy thing would be to change those 2 injectors and see what it does.
My guess is nothing.
Remember the injetcor is only supposed to hold 3000 psi for very short term, like 2, or 3, or 4 milliseconds before it discharges. A gradual slow leak doesn't seem bad. I can see on the flow bench when I crank up endless volume of oil at that pressure, if there is a Poppet issue it pukes out that port a LOT. THEN that injector needs to be replaced. But the slow leak you show just doesn't seem like a big deal to me.
I honestly think if there was an issue somewhere you would not be able to hold that much pressure for that long in the first place.
At what psi do they start to leak from the larger discharge port?
Next thing to try, which I probably did not mention, was to hook 12v to the solenoid and quickly pump up and see if it will hold psi with the Poppet in the UP position. You have to work fast as you don't want to heat the solenoid up and you will if you hold it energized for very long.
Rig up a plug and switch, pump up psi to 3000, flip switch and pump up again to see if it will hold psi.
The Poppet could have issues in either UP or DOWN position. For me I have had as many problems UP as Down. Easy to see on the flow bench, more difficult hand pumping.
Good luck.
