Odd clicking / ticking
So I have been noticing a 'clicking' sound in certain situations coming from the engine. It only does it while driving in the first minute or two then goes away. It begins when I hit 2,000 RPM, so if I can keep it lower than that it never happens. This is a problem since I live in the country on a major highway, and need to get up to speed quickly. Does not do it in park if you rev the engine over 2,000 rpm - which makes it difficult to pinpoint. Best I can figure it's coming from the engine but more exact location is impossible. I am familiar with the sound of an exhaust leak and sticky lifter - this doesn't really sound like that though. It's strange but the closest sound I can come to it is the sound a baseball card makes in a bike wheel, but more 'hollow' or 'echo' sounding?!? I know that's really weird and vague, but that's what it reminds me of. No codes. Stock v-10 with 204,000 miles, always well maintained.

You are describing the sound the injectors make when you have low fuel pressure.
I would check fuel pressure and if low i would suspect the fuel pressure regulator.
but thats just a guess from this side of a glass screen. ( although it was the cause and fix for my neighbor we fixed a few days ago ) it’s not an easy diagnosis to make via the internet.

That's worth a look at least. Unfortunately, my Forscan account seems to not be working right now. Not sure what the problem is. I have not used it in quite awhile maybe I need to reactivate. Also, it makes this same noise (but much louder) when the transmission grabs 2nd (I have 3.73 gears) when pulling a hill and towing my 10K camper when it screams to 4K+ RPMs. It is actually really loud then, sounds more like marbles rolling around under the hood but amplified 1000 times, if that makes any sense. BTW, it has done this ever since I've owned the vehicle (over 7 years) and of all the vehicles I've owned I've never heard anything quite like it before.

That doesn’t sound anything like a injector ( at least not a gas one ) but maybe more like a cracked flex plate or torque converter.
but again, Diagnosing noises via the internet is just guessing. Best to let someone here it in person

The timing chain has plastic wear plates on the tensioners. If you change them, put a new oil pump on. Check out Fordtechmakuloco on youtube. He has videos on the modular engines. Might be a 5.4 in the video, but the timing chains are identical on the modular engines. If you do it yourself, there are tools you'll need to buy or rent. I did it on ours, it wasn't that bad of a job. It really ran smooth afterwards. If the plastic is broken off the chain guides, they will plug the oil pump screen. You'll have to remove the pan if the plastic is broken and in the oil pan.

It isn't a bad job to do the timing chains and tensioner, but it is time consuming because the entire front of the engine needs to come out. You will need the cam lock tools to lock the cams in place when you go to remove the chains and you should get the crank lock tool also. These are an interference engine so if the timing is off say goodbye to your engine.
