Well I think it's most likely the cam phaser it runs as good as it normally does and I don't see any shavings in the oil. I might as well just leave it alone and put on an off-road midpipe to distract me from the annoying noise.

Just check the cam and followers close if you pull the valve cover off. Phasers make more of a knock at idle. Then go quiter when you load the engine a bit. Phasers are easy to replace. You don't need to pull the front cover Ither, there is a special tool to stick down the chains and depress the chain tensioners so you can do them in the car

I'm currently investigating with the valve cover off. There is no timing chain slack whatsoever and cam phaser looks ok. Plus this noise is always there regardless of temperature, rpms, etc. which leads me to believe it to be the lash adjusters.

I don't see any unusual wear but I'm no expert by any means. Pics going up soon.

Did you make sure its not an exhaust leak?

You will need the special tool to pull the followers. The needle bearings under the roller are what spit out. It will still roll but allow for too much valve lash making the ticking sound. You may be able to roll the engine over by hand until each follower is on the base circle of the cam. Then reach under and wiggle the followers. Of thee is any movement then investigate that follower and adjuster set carefullu

When you mentioned this I had an epiphany after seeing everything else looked proper, the muffler on that side is hanging freely do to ghetto rigged tail pipe hanger breaking. the hanging tail pipe is probably what stressed out the exhaust manifold area. So I put everything back together and cut a piece of water hose to start listening to everything. I put it over the cam cover bolts everything sounded fine, it took me a while but I finally pinpointed a slight wind sounding noise coming from one spot in the exhaust manifold so im 99% sure this is what the problem is.

Also I don't ever neglect maintenance when it comes to this car, there was not a single spot where sludge has built up from what I saw and also the inside of the valve cover was clean as a whistle.

Yea spark plugs were all good that's the first thing I checked. At this point I really think its an exhaust leak because when I listened thru the hose I heard a noise that I wasn't able to replicate anywhere else on that exhaust manifold or on the other side of the manifold. It sounded like gas escaping so before I go any further I am going to take care of that by installing new gaskets and most likely some headers.

I got the same problem on my driver side though, i swapped out the lifters put thicker oil with additive flushed an repeated twice also changed out the cam phaser sensor that sits above the valve covers i still have power not slugish like yours the plugs look fine torqued down, checked the exhaust- tighten i have all the tools just not sure what else to check the ticking is driving me crazy Lol

Carefully with the thicker oil thing. Ford has several technical service buillitans out about people putting the wrong viscosity oil in and causing more problems. The engines are tight clearance and the thicker oil has a hard time getting thru the passages and through the bearings etc, causing all kinds of problems. Cam phasers are very common on three valve engines.

Horrible advice..

Update: I thought it was an exhaust leak. I had a shop confirm it is not. They said it might be a bad rod bearing from what they can hear on the outside. Idk about that it doesn't sound as loud as the rod knocks I hear. Mystery continues...

I guess I'll start investigating what Dohcfox recommended.

UPDATE: I was inspecting the rocker arms when I noticed one moving freely. Now when it push on the lash adjuster part it wiggles up and down like the rest of them but the rocker arm itself is very loose when I barely touch it it moves freely around. Also noticed the cam lobe eaten up on this one spot. Pics up soon.

Notice the cam lobe to the far left has been chewed up.

How should I go about this repair?? Shoutout to Dohcfox thanks for all the info on helping me diagnose.

The lash adjuster for that valve is collapsed. Any info/tips on how to remove it? Do I need to remove the cam to get to it?

Got the lash adjuster out doesn't seem too bad but replacing anyways. The follower on the other hand is chewed up and the roller is stuck not rolling at all.

Replacing both lash adjuster and rocker arm tonight.

Looks like a perfect time for a cam swap!

^^It would of been but this is my dd so no time for downtime had to get it running safely asap. Id rather spend the money from a cam install for a top end kit for my fox.

Problem solved!!

Bought a lash adjuster and rocker arm from ford for $30 and some change. popped them in changed the oil now its running smooth and quite (as it can get) again.
