    2011 3.5 Valve tap, I think?

    So after my #4 fuel injector failed and was replaced, there has been an increasingly louder "valve tap", for lack of a better description. No codes and the tech initially thought it was just injector noise, but I don't think that's possible. Has anyone run into anything similar? 104k miles on the car. Is it possible a faulty injector? The noise is definitely from a single source, not multiple like injectors. Once on the road, it fades to almost imperceptible, but not quite. It started making the noise prior to changing the injector but has gotten significantly worse in the last 1000 miles.

    Thoughts?
    TIA

    Bad news. For me it ended up being a rod bearing and ruined the motor. Had to scrap the car.
