Turns out while i can hear ticking that it's not quite as pronounced as yours. Im still not convinced it's a huge issue as ive hear plenty of cars that sound like yours that are running fine. The video i took you can't hear the ticking over the whine of the engine.

Im not sure what would cause a louder valve tick form one car to another as the VVEL system in our cars is all computer controlled.

The noise you hear is def not rod knock. You would hear a much more distinct knock coming from the lower end for that and it wouldn't be as consistent. What you're hearing is valve tick and if there were major issues you might see effects like stuttering or lack of power because the valves aren't working right. I would def assume you would see a check engine light if something were truly amiss. you could try hooking it up to an odb reader and see if theres any pending codes.

I am feeling some stuttering. It's very shaky at idle like it wants to turn off.. But that could be from dirty throttle
