Advice on injectors and hpop
#31
Well I decided to go with a local shop call Diesel injection specialists I bought brand new Alliant injectors, stock everything. Only thing they told me that I wasn't aware of is he said number 8 injector is different than the other 7. Something about chatter or something is why that ones different. Any input on this. These guys have come highly recommended locally and I did buy some stuff from them for my 6.0 and was happy

I will let you know, unfortunately probably no pics the guy who's helping me probably wouldn't tolerate the time for pics. He's kind of old school I guess is the best way to describe it. As far as my choice of injectors I'm satisfied with it. Looking around on line briefly 225.00 each for new ones seems pretty fair. I'm supporting a local shop, able to pick them up, he charged me no core charge just asked me to bring them back asap. I debated going over sized but I've never had an issue with any of my 7.3's pulling the way I want and I figure a new set of injectors alone I should see an improvement over the current ones with 226k on them. Hopefully I don't regret that decision. I'll keep,you guys up dated. Hopefully this corrects the disappearing oil. Thanks for everyone's help.

The AE won't be needed however if you fix your dead headed fuel supply, by adding a regulated return. This puts an end to the #8 injector being at he end of the fuel road, so with improved flow the AE is no longer needed to compensate. Again, it all comes back to your future thoughts on upgrades. The regulated return doesn't really give you much by itself, but as a foundation it lets your injectors do more if you ask more from them, i.e., get a chip, bigger turbo, exhaust, etc.

At least that is what I understand

Ok but if I do regulated return later the AE injector really won't change anything but for now it will compensate for the situation. Correct? Right now my funds are getting depleted especially with a chance I may need an hpop yet. On a good note I was able to fix my wife's excursion by replacing the ipr, which I had. So that saved me some $ to help compensate the expenses here.

The AE injector wasn't OE at first, it only became an issue for those who complained about the noise or such. It was a TSB for awhile, if the customer complained. I wouldn't be surprised if a lot were replaced simply because it was a free service the dealer could perform at Ford's expense during routine service calls.
At some point it did become an OE installation, but I don't know when. I also don't know, as you mentioned, if it impacts performance if you were to get a chip later.

Well we started the injectors last night. Have all 8 new ones in, just have to seal it back up today. 6 out of 8 had very badly deteriorated middle o-rings. Cylinder 7 had just a tiny bit maybe. 8 had none. 3 and 5 were by far the worst with the rest close behind. Cups all looked really good. Cylinder 5 had a non oem injector in it. The rest I believe are original. I took a few pics of the o rings I'll post when I have more time.

Both of those are the top 2 reasons. You are on the right track, we look forward to the pictures.
