The sound in the attached video was intermittent for a while, but has now come back to be consistent, but I can't tell what it is. The sound, to me, doesn't sound like valves, nor does it sound like the typical TCT. The only way I can describe it is like a fluttering of a card in bike spokes, with the frequency increasing as the engine speed increases.

Any thoughts, not wild guesses, would be much appreciated!

Sounds normal to me

 

The ticking noise is kind of faint - almost like injectors clicking

 

Well first these cars have loud valve trains and the injectors do tick. So keep that in mind. I'm no expert at all and def wait for other responses. But from the video I don't hear anything out of the ordinary
