Stiction Gone

Well, I pulled my injectors to change the o-rings and seals. While I was in there I pulled out the spool valves and cleaned them. I saw a video on here that promised improvements to stiction after that procedure. Worked like a charm, stiction is gone!

Worth knowing is that a few months ago I put in Archoil AR9100 and it significantly improved my stiction. This solved it!

I was also having a long crank problem, and I updated my standpipes, dummy plugs and STC to try and address the problem. Bummer is I still have the same issue, but at least I did the preventative maintenance!

This sounds like what I need to do. I am new owner of this 05 and even here in south tx with 80* mornings, my truck needs 10 min to warm up. I read after the fact that T6 would have been a better oil then straight rotella 15w40 and the previous owner was running T6 as well. The stiction is much worse with fresh 15w40 oil change. Looks like I will be changing back to the pricey T6 and cleaning my injectors, etc...

Thanks for the post, I wanted to try Rev-X or Archoil before getting too involved, but looks like it's inevitable! LOL

Good stuff Iceman.........when the time comes I will do the same instead of doling out money for new ones.

Sean did you run the engine with the valve covers off ?? You gotta have a injector o-ring leaking on and off.

Hey Mark,

I hadn't been checking back and I missed your post. Thanks for looking it over...I didn't run with the valve covers off.

I think I may just have a long crank sometimes. It always fires up, and it seems like I've checked everything

This is probably a dumb question but when i had to replace one of my injectors I had the dealer check the rest and they said that #1 and #7 were starting to "leak down" a smidge. Does this sound right? First diesel so I am still learning. Also, when it comes time for the injector change is it pretty easy? I am fairly mech. inclined but for sure no expert.

If you are used to wrenching its not too tough. I found a very detailed YouTube video that helped me a ton!

Here is the link
6.0 Liter Ford Powerstroke Injector Replacement, part I - YouTube

Your tech probably performed a leak down test which measures you injectors ability to hold fuel pressure. If they are not holding pressure, you could have one of a few problems. I'm no expert here, so maybe do some homework. Search "leak down test" on the forum and I'm sure you will learn a lot.

You should ask them how they did it. If they pressurized the oil rail it is quite possible the seals are weak.

Here is a good video of an 03 with an injector seal problem. Is this what they were referring to?

I don't know what other tests are available for a dealer to diagnose an injector other than using the IDS software and a few observation style tests.
