if you cut grooves across the barrel of the spool valve, the injectors cannot, and will not fire.
spool valve travel is only .017 thousands of movement. cut a groove in that valve will cause a direct pressure leak to the exhaust ports, and to the coils. spool valve is now junk.

Did you get the archoil put in?
I put in the cleaner this weekend, so the AR2300 is in. I've noticed no difference in the way it runs yet. I'm going to try and run this for a few miles before changing oil and going with T6 and the 9100.
I swapped a few FICM's around too. I have one that tests at 48+, but seems to be weak driving the injectors anyways. It really made my sticky injector stick out. Until it's warmed up it basically has a dead miss on that cylinder. Hooked AE up, getting a contribution code for cylinder #2 now. After the truck was warmed up I did a buzz test and all passed though. I will try the buzz test again today though with it cold and see what happens. I did take that FICM off last night though and put a different one on, idled way smoother and quieter. That FICM is just possessed.

Awesome links, thanks for sharing! Too bad Ford wont sell us those individual parts for injectors.
The 2300 I got from G Racing arrived earlier this week. Just haven't had a chance to do an oil change yet.
Mike - interesting idea, and I like it. I may go one step further and send in 3 samples, just for grins.
Sample 1 - oil with 5k miles on it, no additives (oil I'm changing today)
Sample 2 - oil with <1,000 miles with Archoil 2300
Sample 3 - same oil as Sample 2, but at 5,000 miles
All samples would be Valvoline Premium Blue Extreme 5w-40.

That would be a great idea to get an idea just how much it actually cleans
Kinda curious to see where that goes as well. Changed my oil yesterday and added 1 oz of Archoil 2300 per quart of motor oil (in my case, this is roughly 20 oz of Archoil). Started the truck and didn't notice an immediate improvement, but I'm not worried yet. For starters, I replaced my fuel filters a few days ago and have been fighting a bad o-ring on the HFCM drain plug. Low fuel pressure = unhappy 6.0. Just to be clear, I had symptoms of stiction before I messed with my fuel filters and I'm confident the two are unrelated.
I'm also thinking (hoping?) that the 2300 isn't going to magically remove varnish, etc within 5 minutes of being added. Probably going to have to do some driving first, and I'll keep everyone updated.
And yes, I did take oil for a sample.

Didn't read it all
But has anyone tried diesel fuel in the crankcase. Right before changing oil?

I was just told a few days ago that a local shop told a customer of mine that they rebuild the 6.0 injectors using a new "Spool Valve Kit." Never heard of it before, anybody have ideas where/how it's obtained? I will try to find out more about this.

only thing that i have heard of new spool valves would be that motorcraft injectors get a new spool valve on every injector that gets remanufactured.
i have an ultrasonic cleaner that i need to try cleaning a set of spools with to document improvements. but polishing with crocus cloth may be the most cost effective option for the DIY people so far.

We use a sonic cleaner on our injector parts, and although it does a very good job, it still doesn't clean as well as a little elbow grease and some polishing.
Exactly. I have some parts from my veggie system that work the same way. Super tight tolerances, they get coked up with veggie after some amount of time. I tried doing a heated ultrasonic clean on them and then put them in an oven to dry everything out and every time I ran them I'd get a little more coming out in the oven. Finally had to figure out how to disassemble them and then clean them really well in pieces. Even then, a little elbow grease helped tremendously.
