Default Name that noise!

After running the hell out of my s2000 at the track, i noticed this weird ticking noice. At first i thought it was a pully bearing but got new bearings and now ican rule that out. Sounds like its coming from the head? Thank you in advance.
BTW, checked oil levels and oil was not low.
Also just did a valve adjustment and no change.
Video is done at cold start, gets alot louder while warm

Warm startup, revs to 4k

Usually doesn't start ticking until it starts warming up, but this time i parked it outside for the night and the temperature is around 90 so maybe that's why it started ticking immediately on a cold start up?

WHAT WAS ACTUALLY WRONG:

Im not able to watch your video. Try uploading it to YouTube.
Have you ruled out TCT or needing a valve adjustment?
Did you have an overrev at the track?

Definitely not TCT.

Sounds like a lower end knock.

is there any way to test this? Maybe strain oil out of the engine and look for metal? Thank you for the response

Yes. Drain the oil an look for metal shavings, if it's a spun bearing, there will be plenty.

Tonight, i had the same issue with my car. I was driving on highway i have finished 3rd-4rd gears just before the redline, in 5rd at 6500rpms engine lost power for a second after that i have released the gas and had gear to neutral engine turned-off by-self. Battery and oil lights came on. Now, i have the same noise. If anyone knows, please give us an idea. My car had 55.000km on it.
