So I am back into looking at the oiling system. I am thinking about trying this technique and/or the one outlined by Ricky above. What I like about it is, if I used Sea Foam in the oil lines one at a time and the exhaust starts smoking, it is proof that liquid is going from the omp into the combustion chamber, correct? This at least demonstrates a clear path. What I don't like about it is injecting cleaner into the corner seals where oil should be. Is this safe for the seals/housings? Would it be a possible benefit from a de-carbon aspect? Maybe use something else like ATF?

At idle the force/friction on the seals is pretty negligible. Should be fine for a one time treatment. SeaFoam contains oils and has nonzero lubrifying properties anyway. That's what the smoke is from.
UV dye... Can see it through the lines, but what happens when it burns in the combustion chamber?
My thought with the sea foam, was that as soon as I start drawing it through the oil line, I am looking for smoke out the exhaust. That way I know it made it through the injector.

You already nailed it, it just burns up, end of story. There's dye's out there meant for tracing fuel leaks. I'd be surprised if you do get noticeable smoke out of the tailpipe with your idea. The OMP doesn't flow that much at idle/neutral, even if you do give it some gas.
2) accessed the omp by removing the battery and tray.
3) broke loose all 4 oil lines at the pump. Basic inspection, confirmed they were clean and reinstalled.
4) had a small cup of sea foam ready to dip each line into.
5) started and idled car up to temp. Removed oil injector vac line at the intake and capped it.
6) sequentially unbolted each line at the omp and dipped it in sea foam.
I could hear and see the line draw up the sea foam. I ran about 1.5 oz through each line or about 30-45 sec. as soon as it started to draw the sea foam, the idle dipped and the smoke started. This happened for all 4 lines at the same rate and time. With the vac line capped the suction was strong even at idle. When bolting the line back into the omp, I could hear it draw out oil from the pump. After all lines were done, I let it idle with the vac line capped for about 30 sec. exhaust started to smell less like sea foam burning and more like oil.
Then I opened the vac line back up and reattached it. I ran around 2oz of extra sea foam into the uim. Shut it down. Let it sit and fired it back up. Lots of smoke and lots of revving. Smoke cleared, job done.
well let me ask you this; how would oil/dye make it up the line to the injector without the injector itself working? Where was it going then as the oil/dye displaced what was in the line ahead of it?
nice for you to confirm with seafoam, but perhaps not really necessary to have gone through all of that …

Well that was the issue. I had no way of knowing the line was drawing oil from the pump. If the system was working, I had no way to confirm it. With this test I confirmed two things.
1) Under test conditions, each line independently drew sea foam from the dispenser.
2) Immediately after drawing the seafoam, the engine idle dipped and smoke started to come from the exhaust.
The conclusion is that seafoam was traveling from the omp connection in to the combustion chamber. The only available path I am aware of is through the oil injector. If there is a clear path for sea foam, it follows there is a clear path for oil.
Does this confirm the omp injection system functions 100%? No. This just confirms the lines and injectors are able to transport fluid under test conditions.
… dye up to the injectors does not tell me the system works, just that the lines are clear.
it’s just common sense for anyone with a basic technical understanding
you know, like people running in circles justifying they’re accomplishing something, only proving how hopeless they are so you just walk away and let them keep running.

I tried the dye a while back. It was inconclusive. I was hoping to see it progress up the lines, but the dye just migrated through the oil by itself almost instantly. Yes, the lines were glowing under UV light immediately.
