Ticking sound (Not TCT)

Hi guys, I drive a AP1 facelift Honda S2000 (we didn't get the AP2 in the UK).2 years ago, the bottom end of the engine began to knock which meant it needed a rebuild. The rebuild was completed and then one day blissfully in Vtec at high speed, i started to hear a ticking sound which progressively got louder.In terms of the work thats been done to diagnose:

Taken off the main drive belt.
Timing chain tensioner has been changed
Changed the cams and the valve train.
Set valve lash to 0.08 on the intake and 0.10 on the exhaust side and re-did it again.
Changed oil and oil filter twice with the second oil grade being 5w30.
Looked at the possible alternator bearing.
Looked at the AC pump and bearing.
Checked tensioner idler.
Checked Belt idler
Checked injectors.The sound is still persisting and myself and my mechanic and I are truly stumped.Does anyone have an idea of what this could be? Maybe it means checking and redoing the work although we have done this meticulously.

I cant post the video so hopefully the audio will suffice.

Any thoughts would be much appreciated

Thanks
A lad thats about to give up
