Default injector removal

ok 6.0l guys my cts was giving me a code of #4 injector contribution/balance every time i drive the truck so i figured while im in doing the egr delete would be a good time to replace it im assuming #4 is driver secound from the front correct? also im thinking i have to pull the valve cover any tips would be great to replacing this injector

ok i watched a youtube video injector replacement doesnt look to complicated my question now besides confermation to which injector is when rmoving all the internals do i jst let all the oil and fuel drain into the cylandar?

I would try and keep the cylinder empty as much as possible, vacuum anything out that might fall in. There's barely any room inside there as is, you surely don't want to hydrolock this thing just doing an injector replacement.

#4 is indeed 2nd one back on drivers side.

Agreed... I always suck it out, then clean the hole out real good with brake cleaner and compressed air, and use a mirror to make sure that the hole is clean clean before putting the new injector in. BTW I would recommend doing injectors 4,6,8 as well. sometimes, not all the time... changing one injector will cause a daisy chain effect with the other injectors in that bank. I've seen it happen on almost every other truck that we only do one injector on.

Usually the only way it'll effect others if the job isn't done right and it's leaking past the o-rings. Just make sure the o-rings are not damaged during install.

I would never replace extra injectors that aren't bad already, but that's just me. If the install is done correctly there is absolutely no reason a new injector on one bank is going to wipe out the other 3.

I used to think the same, but after changing one injector in trucks and have it throw codes for other injectors in the same bank make me think otherwise, to each his own but thats my 2 cents. I've even pulled the one I've replace to check for damaged O-rings everything checks out fine everytime. Change all 4 in the bank and never had any trucks come back.

Chances are the one that was changed didn't need to be changed then. They can sometimes throw fault codes for the wrong injector.

So lets say it's throwing codes for injector 1. However, injector 3 is the real problem child. O-rings are shot on 3, and it leaks past and falsely throws the codes for other injectors in the "rail" So you go in and replace 1, cause that's what it's throwing codes for, get it up and running with new o-rings on injector 1 and all of a sudden a different injector throws a code. Did replacing all 4 on that side fix the issue? Sure, but was it necessary? Maybe not. It might just have been injector 3 all along.

If anything, I would replace all of the o-rings on that side, but not the complete injector assembly. Just a bunch of money for no real reason. I also see leaks pop up shortly after replacement due to the injector becoming loose in the hole. Apparently Ford's torque spec for injector clamp isn't quite good enough.

Just my opinion.

Thats a good point, I see where you're coming from and it makes sense. But doesnt it also make sense to be sure that you wont be back in that bank again by changing all 4 if you have the money?

To me it makes more sense to diagnose it properly up front, instead of guessing. If the customer request it, then so be it, but I would feel bad telling a guy he needs to buy 4 injectors when only one or two is messing up. I'm all for fixing things the right way and not doing the job twice, but I'm an even bigger stickler for not spending money on unnecessary repairs. Know what I mean? So for the cost of it, I'd do all of the o-rings on all the injectors on that bank for security. That certainly wont hurt anything and wont break the bank like doing 4 injectors would. I understand as a shop you certainly don't want to dive back in multiple times, and you certainly don't want to try and explain to a customer that you have to dig back in to replace a different injector that didn't get caught the first time because codes are being thrown for the other injectors. It's a sticky situation.

Keep in mind that my knowledge on the 6.0 is extremely limited, But could you not pull all 4 and have them tested
