Ticking sound on my 2012 GC on cold start up

Everytime I start the car in the morning there's a weird ticking noise coming from under the hood. I attached a video. Im not really sure whether its coming from the pullies or from the spark plugs side as seen in the video. Has anyone experienced the same ?



Edit:
The video hasnt been processed. Alternatively it can be seen from instagram http://instagram.com/p/rRoq0iA1uR/

I have 2015 GC Altitude with 4000 miles , and it ticks on cold start -ups, did you ever figure out what it was.

Most likely what you are hearing is valve noise. I doubt it is anything that will harm the motor.

Thanks for your reply, it doesn't sound like valve ticking. I called ticking but could also be described as crackling or popping sound. I plan on letting the dealership look at it , but they want it left overnight so finding time is tough.




Thanks Jon
