Default 5.4 Injectors Ticking

I just got my 2001 Screw with 172k and it has a ticking coming from the injectors. It runs like a champ, just can't stand the ticking. I'm almost 100% sure its the injectors because when you touch them, the sound goes with the vibration. I have also removed the oil cap while running and the sound did not get louder so I assume its not the valvetrain. I have ran a hole bottle of Lucas UCL through with no luck. Should I resort to new injectors or is there something else I could try? Would changing the o rings help anything? Sorry if this has been covered before, I used the search function but didn't find an answer specific to my question.

From my understanding these trucks like the injectors to tick. I would also look at exhaust leak though

So its normal for them to tick? It seems like only some on the passenger side tick though. How can I check for an exhaust leak? The previous owner assured me it wasn't the manifolds and that it was the injectors, but for all I know he could be wrong.

It's fairly normal for some ticking from the injectors due to the pulse widths. To check for exhaust leaks, look for black marks around system and with a cold system take some soapy water and spray all around the suspected area. Roll over the engine a few times and see if any bubbles can be seen.

Alright, its not the exhaust, so it is the injectors. The truck has all stock exhaust so it just makes the ticking that much worse. Would you guys recommend replacing them with remanned ones or is there a trick to stopping the tick? O-ring replacement? The remanned injectors have a lifetime warranty btw. Thanks for all your help thus far.

Unless they are causing misfires there's no reason to replace them due to the sound.

Its loud though, sounds like a sprinkler system is running my truck lol. Would it hurt to change them out or will I most likely have the problem with the new ones? I understand its normal, but this is the first 5.4 I've personally heard do this.

Probably won't hurt anything to change them, just make sure the new ones are the same lb/hr rating.

I find it hard to believe injectors can make enough noise to be heard when driving. Check your exhaust manifolds for broken studs. The passenger side rear most studs usually rust off or break due the the manifold warping . Get a good flashlight and look throught the wheel well. I've replaced the passenger manifold on three of these motors.

Also make sure you don't have a spark plug backing out, that will give you a ticking sound before it blows out, stripping the threads and destroying an ignition coil. Very common on these motors.
