What's a pretty slow tick-tick-tick sound that DOESN'T seem to go away, then? About two ticks per second idling I'd say?

Audible with hood up, less audible standing in front of truck, inaudible from cabin...

Temps stable, fresh coolant fresh oil new plugs new coils, no codes

There at the end of the video is Roughly how a normal 5.4 sounds, still ticks after the job. before you’ll notice it is a way heavier tick almost a “knock” if you listen below the truck.

Well that's not 100 percent accurate on the overhead cam part, true it doesn't have a lifter like a pushrod motor, it uses cam followers, along with oil fed valve lash adjusters, that are similar to regular lifters in the sense that they have to be functioning proper. What happens on a lot of 3 valves is the back cylinders get starved for oil, due to low level, or partial failing oem pump. They seize in their bores, then the noise and performance party starts. Back to earlier, regular maintenance, proper cooling alleviates a lot of these issues.

I read people using additives, 10W40 or 20W50 or other wrong weights, destroys the top end and timing chains.

I once recommended a small amount of marvel mystery oil, usually a great product. But the op went overboard on my suggested amount, and his motor went into cardiac arrest! Luckily it was one of his outside sensors that had a mild stroke. This was about a year ago, and a lot of schoolin on these motors. I wouldn't put any thing but good ole 5/w30 oil in these motors. It's like a doctor prescribing something, you never know how your patients gonna react!

Nope both are still quite atrocious and far worse than mine

Nothing atrocious about it, sounds fine the last 20 seconds they show after the job.

Mine sounds almost just like the second one. Lots of ticking injectors (you can hear it on the fuel rail with a stethoscope) but mine has a bit more of a “lope” to it. Maybe I need new solenoids.
