Finished installing a Billman TCT, valve adjustment, new spark plugs, and passed compression test. I heard the s2000 has pretty chatty valves and injectors. Looking for some reassurance if this is a normal sounding engine.

Take another video.

5 feet away from the front of the car, hood closed.

 

Hard to capture the sound but some videos as requested.

Honestly it sounds like mine. I had a valve that was loose after adjustment and I could hear it as the rpms came up to 3-4K. But I don't hear anything out of place on yours while idling.
