Yes, as said before:

Sounds occuring only in warm engine conditions is - let´s not say good, but - better sign. Quit possible due to wrong adjustments made.

A rather loud, metall sound repeating up to 3 times per second is axial clearance of the camshafts. They bounce from sides to sides making that noise.

If you hear high frequent "click" sounds, the cam chain (stearing chain) which drives the camshaft might not be configured the right way. And the valve open/close not exactly the way they are supposed to do.

There´s the possibility, the chain longened due to wear, or the camchain tensioner might have a scratch (change!).

You might want to go to a dealer and get that check, since broken camchain tensioners can lead to fatal engine failure.

...Or the clearance for valve adjustment are WAY out of tolerance, this is eligible for home-checking. Check the video below!

EDIT: Some members of quite bigger experience than me wish to have a soundfile, that covers the whole bandwidth of rpm, including reving up the engine and so on.
