Typewriter noise

Ok changed my oil a couple of days ago and now i have this annoying noise coming from my truck. How long does this usually last? Anybody found a way to avoid it?

Ford posted a bulletin on it, it is normal and will go away after 200-399 miles if not sooner

It might be the def pump emptying the def from the lines back to the tank. Even with deleted tuning the def pump still does this process after vehicle is shut off.

I read that it goes away after a couple hundred miles. I changed it myself this time. Don't know if that makes a difference. I don't think it is the DEF tank. The noise is definitely in the front of the truck.

Just put 2500 miles on my truck going from Florida to Tennessee and back. Still sounds like a typewriter. Can't hear it inside the cab, but no mistaking it when you get out. Ran like a top the whole trip and averaged 17.5 MPG, which included a lot of mountain driving. I don't want to put it back to stock so i can take it to the dealership. Any ideas?

Everything that I have read or heard was it should go away after a couple of hundred miles. The one thing I am wondering is this is the third time the oil had been changed. The first 2 were at the dealership and the this one I did. Never had this problem when it was done at the dealership. I can't imagine they do anything differently. Pretty straight forward job.

yes i agree i also just read that it could be air in the fuel pump i also drained the water fuel conditrioner on the same day but i leading to beleive the oil change did it

[LFD132]

Sounds like we performed the same maintenance. I agree i don't think it has anything to do with the water separator being drained.

Just curious, are both you guy's running 15-40 wt oil? I heard the factory fill is 10-30 just wondering if the heavier weight oil is adding to the tapping noise.
