Civic FD 2011 noise in the morning

[pacogun]

Never heard of it before. Where does it sound like the ticking is coming from? Engine bay? Below your legs?

Hi Baygon,
The noise is from engine bay. I opened the bonnet, definitely from the engine. If I sit inside the cabin, I describe the ticking sound like the sounds of pedestrian alert (you know the tick-tick-tick sound on pedestrian crossing to alert vision impaired people) from inside your car with window closed.
Oh, and also only noticeable when the car STOP IDLE. But when car is moving, there is NO noise.
When temp reach half, no more noise even when the car stop and idle.
