2006 is makin a knocking sound

gotta 06 thats got new injectors, egr system, studs all the typical jazz on a 6. to make em last forever... day before yesterday i noticed a very very slight ticking noise thats not typically there, so yesterday i drove on down to wide open performance in sandy ut. (they built the quad turbo 7.3 rail dragster) they are pretty much the authority on the psd in utah (that i know of anyway) and had zane take a listen to the noise, he informed me that is sounded like an injector knocking and to put a bottle of atf in my fuel tank and that should clear it up, wtf? is this the remedy? the noise is there at idle but cant hear it when i give it some throttle. before i go dumping atf in my tank i wanna make sure im not going to hurt anything. im halfway through my oil change miles (2500) so ya any insite is greatly appreaciated! sorry for the book but i cant afford to buy 1 injector right now let alone 8! or any other broken part! im freaking out!

atf will just lube the pump/injectors, if the injectors are that new shouldn't they be warranty?

unfortunatly no warranty, i just bought the truck a couple months ago and the warranty is only good for the original purchaser (not me) thats the story i got when i called the previous owner to get the number for where he got the injectors, did this before i bought the truck (bought the truck from the dealer he traded it to). cant remember the company name they are out of california name starts with an s if memory serves me correct. i called the company to confirm and previous owner was correct.

that sucks. if its running fine i wouldnt worry about it. never a bad idea 2 run some rev-x in your oil tho. that will help your injectors out.

really how would you know where the noise is coming from? the oil pressure there is to push the fuel into the cylinder by pushing on a piston. Theres not really any metal to metal contact there except for the piston against the cylinder wall in which the oil will lubricate. All the moving parts are on the fuel end of the injector where you don't really receive any lubricant due to low sulphur fuel. That's one reason why all these companies that create fuel conditioner add some kind of lubricant to help lubricate your injectors (ie extend life of injectors from wear) because diesel fuel is dry. Also maybe you should like at the times of the replies, when i clicked reply nobody else had commented on this thread, we both replied at pretty much equal times.

Even if he did add a bit of atf to his fuel what would it hurt? It could possibly quieten his injectors up, lube his injectors, and maybe create a BIT of smoke.

Are you running Syn oil and if it real cold switch to a 5w40 Rev-x would be a good shot add cetane boost to the fuel may help, just remember ATF will turn the fuel red

I dont know where the noise is coming from just making an educated guess. 6.0 injectors are prone to oil side failers..... read a little bit. thats why everyone is running rev x that has injector stiction.... not bc of the fuel side....the only time you see fuel side issues is when you run dirty fuel, or prolonged low fuel presures. thank you sir, have a nice day. did i mention i am a diesel tech?
