Default Engine ticking on rpm up and down

Hi i am new to the forums but have done extensive research into what engine ticking can be. I have heard it can be fuel injectors, lifter arms, among other things. It seems to have progressively gotten worse. And I have only had it just over 2,000 miles (@126k]. 2006 non turbo. Done oil changes and tried marvels oil as well per many good reviews on here. I just made a video of where the ticking seems to be coming from. Thanks in advance.

is it as loud in person as it is in the video?

any change in sound when it's cold versus when it's at running temperature?

Yea it ticks pretty loud in person as well. Almost sounds like a ball bearing tapping around. On a cold start, revving the engine is much more pronounced than if you have been driving for 20 or so minutes.

is it louder in back of the engine than in front of it? exhaust manifolds crack on these and can make a loud ticking too.

Also no check engine light and it drives beautifully. Seems to be a small leak in the radiator, hopefully from a hose, haven't checked it yet. Refilled with proper hoat engine coolant when it got low. No milkiness.

It seems like it is coming from where I pointed the camera. Possibly up front. Really hard to tell.
