When I replaced my orings, I doubled up the steel top ring. I set the ring gap 180°. With the double steel ring, there is no play between the top oring stack.

Is there a better injector o-ring fix
- Thread starter gnxtc2
- Start date
I've had to pull about 10 sets of injectors in the last 2yrs for this o-ring BS...
Most were from the same place because O-rings were already installed on the reman injectors.
However, I believe I'm having a few trucks showing some signs of issues with APs I used a while back too.
I haven't had any come backs "yet" with motorcrafts but only switched to them exclusively about 6 months back.
I wish whatever dog sh!t factory this bad batch is coming from would get their **** together. It has cost me thousands because of the dumbness.
I've ate 3-4 wrecker calls for my customers when trucks wouldn't start, all the labor and ALL the o-ring cost on every truck. It's getting old...:fustrate::fustrate:

Is this just in the last few years? I have never had a problem with International or Motorcraft O-rings. I ran higher ICP then most people and put 150k on a set of Motorcrafts, they looked damn near perfect when pulled out.
One thing I did do was clock the gap in the metal ring so it didn't line up with the oil port in the injector bore.

I just ordered a set from riff raff because I think that's what's going on with my truck. I'm expecting to see the same cracked o rings when I pull the injectors.

It is highly unlikely that high HPO is the cause of failure. We have customers who ordered stock reman injectors last year and have no tuning at all, that have blown the o-rings up top.
Joey at Terminator also runs extreme ICP (around 4000psi I believe) and he does not have injector o-ring issues.
This is an industry wide issue. Not singled out to a certain injector builder. A manufacturer of these o-rings released a bad batch of these things. The issues seem to be resolved now (as long as you are using OEM o-rings).
From what I have seen, injectors ordered any time last year or the very end of 2013 could have o-ring issues. I am sure the injector builders will know a better time frame though, since they are the ones sending everyone o-rings.

Depends on the builder, but if they say anything but Alliant/Motorcraft/Intenational, (all of those are Alliant), I don't know that I would trust them with building my injectors.
So, Through research, we knew that there were two people still using AOL. We now know who one of those people are.

The only way to get a new set of AC injectors is through Alliant Power, they come with o rings already installed.

Got my injectors pulled finally and 6 out of 8 had broken o rings the last 2 weren't in very good shape either.

Consider the suspense over, I'm the other relic from the past.
I got a new set of Alliants ACs from Clay. So I take it I'm good to go.

I get hassled at work to why am I still using AOL. Then I ask what is wrong with AOL and why should I change? The answers I get is because AOL is old....that answer is not good enough for me. Plus, knock on wood....my account was never compremised. All my friends that have yahoo, gmail, etc, etc get hacked all the time.

FWIW, We only use Alliant Power orings and have not had a single failure that we are aware of in 10+ years. We only use one steel, as we've found no benefit to running two.
There are orings available from at least two other manufacturers that appear like Alliant orings, but do not hold up as well. We see them come in on cores all the time and they're blown out. The Alliant Power orings cost us a few more dollars per injector, but it's worth it in a case like this where you guys are seeing multiple blowouts on some other remans
