"The throttle plate is never fully closed so when the engine is idling there is a vacuum in the accordion tube." - EPIC FAIL
hook up a gauge to one of the ports on the throttle body boot and report back how much "vacuum" your car makes at idle..or any rpm for that matter...

I am not doubting the seafom making it through the injectors, I am doubting it doing anything and fixing a stuck injector. Also as 9k mentioned the liquid would take the path of least resistance.
The only solution is to buy new ones or used ones that aren't failed. You can attempt to clean them but that will require soaking them in parts cleaner for an hour or so then spraying them with carb cleaner.

Oh, and you didn't respond about there being vacuum at the intake side in front of the throttle plate. Are you going to admit you are wrong? Or are you still standing by you "epic fail" comment?

I don't have to do it to know it won't work. I understand the system. Obviously you do not understand it based on your comments. The throttle plate is never fully closed. When the engine is idling there is always a vacuum in the accordion tube. How would the engine run without any incoming air? Not to mention that as soon as you disconnect the hose from the accordion to pour seafoam down it, the engine would stumble due the vacuum leak unless you plugged the hole in the accordion tube.
Why do I have to keep repeating that? Is this really that hard to understand?

Since there is only a very very slight vacuum in the accordian tube, the engine only develops a slight miss when leaking from this point (only at low rpms though..)
I'm sure you already know all that though.
there is venturi vacuum in the accordian tube only--not a true vacuum as normally thought of in reference to the engines health.
The omp system does confuse me. I do know if you remove that intake line from the omp your car will use a lot more oil. There is actually a TSB on it.
there is a check valve in an omp nozzle and maybe that is what is clogging up?
It should be easy to do a test--just hook up a vacuum tube to the end of one and see if it is open?
This would be worthwhile confirming---because if it does work then that could be a VERY helpful thing.
By design I agree with 9K (lol 8K just kidding) that it is not supposed to work, but i have seen stranger things and the man says his attempt did work.
Anyone have a nozzle laying around?

Man, I keep getting sucked in 
I have a few laying around and I understand what you are saying about the way things should work and the way they actually work. I understand he believes his test worked because his car started to idle rough and he smelled the seafoam burning
But here are my questions.
1. Did he plug the open port on the accordion while doing this "test"? He didn't mention doing so, so I doubt he did. That alone would cause the idle to decrease and the car would stumble from the vacuum leak as soon a she removed the hos e from the accordion tube.

Sure didn't.
I think long enough for the smell to go away after a few revs would be a good call.
I did the same right after work. Here are my results, please share yours too.
Also, It did smoke this time but only on the first rev, wasn't much.

Wrong thread (I guess) but thanks for finally answering my questions. My car nearly dies when the tube is removed from the accordion tube. Weird.I still don't understand how there is full vacuum (there should not be) of 15 at the oil injectors but your video speaks for itself I guess
Now I will definitely be doing this when I get home
Are you consuming any oil at all?

I understand air is always flowing while the engine is running. But the only way to create a readable vacuum is to have some type of resistance. (exp - clogged air filter).
Since there is only a very very slight vacuum in the accordian tube, the engine only develops a slight miss when leaking from this point (only at low rpms though..)
I'm sure you already know all that though.

^ Na man its not like that. I just want facts, I'm not the smarts person here. But you can see why I want to discuss it, with the end result being a fact. Wouldn't it be great if this actually could help someone with low oil consumption problems, and prolong engine life?
@9k -
Yes, but very little at first. In fact so little I called my only friend with an 8 (owned it for about 5 years now.) To see if it was normal, he said it sounded a little low but it could be my driving habits.
The first 300 miles on the car I changed the oil 3 times to get sort of a flush.
After...
I burned about....
- 0.5qts in 2,000 miles. (5w-30)
- 0.8qts in 2,000 miles (5w-30)
- 1.5qts in 2,000 miles (10w-40) (I performed the first try somewhere in this oil change)
- 0.5qts in 800 miles (10w-40) (Current oil, will be checking level next fill-up)
-Edit-
Driving habits are pretty normal for an 8 owner, I think. Warms up for about a min maybe less (summer time). Very light driving till about 15mins into my trip. 4-5k normal shifting/driving. +8k pull maybe every other day, or when/where permitted.

But on a serious note, wasn't there a TSB regarding installing a series II accordion tube on a series I resulting in excess oil consumption? This was due to the fact that there is engine vacuum applied to the oil metering nozzles. The tube on the intake is there to counteract the engine vacuum with intake manifold vacuum. It makes sense to see vacuum on the OMP side.

Your consumption seems normal now. It doesn't seem normal for there to be that much vacuum at the oil injector nozzle at high RPM, seems like the oil would be sucked right out. Beside everything i have read indicates there should not be. However, what should be and what is are two different things.
If I'm wrong, i'm wrong, it's no skin off my back so long as I learn something.
Now I'm off to go prove you wrong!!

Thank you Shawn!
you have confirmed everything I have said...
1. there is no vacuum in the throttle body boot, that was pretty obvious but some had doubts :-)
2. there is vacuum on the OMP nozzles hose that connects to TBB
3. seafoam sucked in this hose makes its way trough OMP nozzles into combustion chamber
some of you might wonder how is the vacuum in the OMP hose created when there is a check valve on the nozzle. it is simple one way check valve is there to prevent things going out of the nozzle trough the port #1 but it allows engine to draw the air trough the same port therefore creating the vacuum..
so running seafom trough OMP will be beneficial for the nozzle cleanness which is critical for proper lubrication of the engine seals.. I would recommend this procedure as a part of regular maintenance on our cars.
Shawn one recommendation for you: run synthetic oil in the car, ester based if possible.

Ummmm guys
In that video I believe that was the Jet setting line not an omp line
I'm almost positive the yellow marker indicates the jettin line ... maybe that's what you guys have been talking about the whole time ... but I thought it was the OMP line ... which has a white mark ...
No?

I'm pretty sure you're using the right tube. If you look at the illustration (buried somewhere in this thread), the tube on the intake boot that is furthest to the right goes straight to the OMP. The middle one goes to the intake manifold.
