Injectors, days are numbered?

Hey guys, I am currently working on a 2006 6.0. just finished a few injector buzz tests and found injectors 3,5,6,8 being inconsistent when cold after started and ran for a few minutes repeated buzz test they all hit except for 6. Obviously number 6 is going to get replaced but my question is should I replace 3,5 and 8 Are they getting weak it's a work truck so the cost isn't really an issue.
Thanks Brent.

A general rule of thumb they say- If you have an injector on the left side of motor say #4, and #6, the most reliable repair would be to replace that whole bank(2,4,6,8)... When one injector goes- normally that associated bank of injectors start to follow. In your case i would recommend replacing ALL of them being that you have injectors on the left and right side of engine giving you troubles.... If you do replace all the injectors and as you said cost is not an issue, replace with new re-manufactored alliant injectors. You cant go wrong with new injectors. Never had an issue with mine... Another option if money was tight would be to switch to 5w-40 synthetic oil and add rev-x.. Although i have never used an oil additive and will not use an additive because it is just a bandaid fix. Just another option to give

That would depend on if they repeat showing up very often then changeing them would be adviseable. Also how much that truck is relied on and how much danger would someone be in if it left em stranded. A truck that works out in the middle of no where is not something you want to be stranded in this time of year especially should you be at 10* below 0. Not my idea of a fun time. People can die in that kind of situation.

When I had 2 go on 1 bank at 50 k I was going to pony up for the other 2 and the dealer stated it was a waste of my money now at 90k I am glad I didn't

I run Rev-x sometimes and synthetic oil all the time

I would suggest checking your fuel pressure, I agree with only needing to change the bad injector, unless of course all the injectors have been starved of fuel or pressure for a considerable amount of time. Jmo.

Sent from my phone that somebody didn't help me get.

Thanks everyone for the input it's much appreciated. By the way is anyone else having to remove the A/C evaporator cover to get a torque wrench on the oil rail on the pass. side?just wondering. Also, been hearing a lot about rev x and how injectors really like the stuff. Was thinking about using it in my personal truck( also a 6.0) just as a preventative measure. Does it really live up to the hype?
