Tick Tick Tick .... Need help with this sound

I have this strange Ticking sound... I notice it at stop lights and such, oil level is ok and it doesn't seem to change rhythm with RPM.

I took a video as I know its hard to describe in words and the video is hard enough to hear it but you can heard it best at 15 seconds to 30 seconds until I shut the motor off.
Then after a restart Tick can really be heard starting up again at 1:56, it does take some time after a start before I hear it again.

FYI HVAC was turned off and its not the fan.

Thank you everyone for your help.

RE: Tick Tick Tick .... Need help with this sound

To me it sounds like the fuel vapor purge valve cycling ...on my older 1995 model it is located on firewall under hood in line with dashboard in vicinity of wiper motor.  I have never heard it inside vehicle...but have not been listening for it either.

 Here are some others that have recorded:

Re: Tick Tick Tick .... Need help with this sound

I have a ticking sound at start up, coming from an electric solenoid attached to a vac hose..located on the drivers side, under the brake booster.

Mine has had tick tick tick at idle for 7-8+ years. Might be nature of the beast. I believe it is the nature of the beast. If its not a knock you might just be hearing an emissions related noise or maybe just valvetrain?

RE: Tick Tick Tick .... Need help with this sound

Did you ever figure out the cause of the ticking? I have the same annoying ticking. It doesn't change with rpm either.
