Got the truck used, it had a rough life. oil was pretty dirty.

I have changed the oil several times and used sea foam in the oil to help clean it out after noticing the issue.

Noticed it having a random rough idle. Fuel economy has been poor, and more sluggish than previous 6.0 trucks i have owned.

Then noticed a little noise coming from the VVT phaser area under the water pump at around 2,000 rpm. Like a tick of sorts. (can't hear it from the cab, only while having the hood up)

It isn't throwing any codes which surprises me because if I look at the cam spark advance is seems to jump around and be erratic.

I don't know what is normal and haven't been able to find much info on it.

Trying to figure out if I need to replace just the solenoid or solenoid and phaser as well.

Check out the scanner log and let me know what you think.

Thanks in advance for sharing your knowledge.
