Ticking during idle, thoughts?
#11
I can hear the tick, it is low frequency at idle but not bad as far as the sound (at least what can be made out via a web video, not in person)
It is likely valves or injectors. Valve adjustment is always the number one step. Improper VA is definitely possible.
A long skinny screwdriver makes the best stethoscope to listen to injectors.

To answer some questions the VA was done by a very reputable shop (could still be the reason), the TCT was done by me and I did remove the pin, and I tried the cardboard tube listening trick and am not sure I have pinpointed the location of the ticking, but my S did whisper sweet nothings into my ear and I felt she almost seduced me onto my garage floor (...#MeToo)
In the process of elimination, there were a bunch of things done at the same time, that may or may not be related but worth mentioning.
2 weeks ago in one day I did the following:

2 weeks ago in one day I did the following:
- Disconnected battery
- cleaned IACV, replaced gasket, (removed black motor box and correctly cleaned, using Honda Throttle plate cleaner)
- removed throttle body and cleaned, replacing the gasket, using Honda throttle plate cleaner)
- Replaced my Ballade TCT with a Billman one (for no real reason other then I felt it would be a piece of mind)
- Replaced the Solenoid VTEC gaskets (2 of them, using the Kraken one)
- Idle relearn procedure, went for a decent drive, (all idling issues were resolved)
- Added half a bottle of Redline SI-1 Fuel Injector Cleaner with a gas fill up and headed home
- Replace the two hoses and do a proper coolant flush as I didn't know how much I lost or if air got into the system
- Oil Change with Redline 10W-40
- Valve Adjustment
- Drove the car around and with the next gas fill up added the second half of the Redline SI-1 Fuel Injector Cleaner

Update: I haven't had a chance to attempt a VA on my own until next weekend, but I did get a good mechanics stethoscope, and I have another video below that really captures the issue. I can hear the ticking in the valve cover area, but not able to really pinpoint it, the injectors all sound the same, very loud loud like someone is pounding a small ball peen hammer on a pipe... (is that normal?). Not knowing exactly what I'm listening for makes this a bit difficult.
Here's another video, the first 2 seconds you hear the ticking, then when the fans turn on it goes away (always does that, and with any blip of the throttle) at the :40 second mark the ticking comes back after the fans shut off. If you have headphones it will be very audible.This is pretty consistent in behavior.
I figured I'd take another week of investigating and getting feedback before I start changing things under the hood.

Fuel injector cleaner can sometimes cause gunk to get lodged in the spray needle causing it to tick. If all else fails, you may have to get the injectors cleaned with a more aggressive method.

103,500. I've listened to just about every S2000 engine noise video and it doesn't sound the same, nor with the symptoms I described.

Take a long pry bar or screwdriver and touch things that you think the noise is coming from by holding your ear to the other end. Has saved me tons of time diagnosing all types of different cars.

Here's a true story: I had ticking, changed the TCT, no change. Valve adjustment, no change. Found a minor leak in the header, put in new header, no change. Ended up being a loose wiring harness.
