It just started with a slight clicking about a year ago and just keeps getting worse to the point it sound like something is about to give.
You are running 5-30, is that what Ford calls for, heavier oils will not help only create more noises.
My 3.0 calls for 5-20 and if I run anything else like 5-30 or 10-X it will tell me with rocker arm noise.
I had a 5.0 that had a slight knock when I used higher viscosity oil.
It may be too late but try changing to the oil “in the book” and see if that helps.
Do you know where the noise is coming from ?
What about the timing chain tensioner, when it wears on other engines you can sometimes hear a ticking.
As StxDangerRanger said, a lot of variables without hearing it.
