Is this the timing chain tensioner?

its a fast clunking sound and i hear it the loudest on cold starts in the morning and night (cooler temps). its not overwelmingly loud but it is noticable (to me). kinda sounds like similar to what the fan does on a cold start if you can imagine. anyways, after i drive it, the sound pretty much goes away. no issue w/ anything. its been making the noise for as long as i can remember but it has always made me uneasy. i let the truck warm all the way up before every drive. it will sometimes lightly clunk the whole time till i drive it, which makes me rule out the common oil pressure explanation (never had btw). i stuck a screwdrive to the bottom of the timing chain cover and it is very prominent there. what do ya think? should i be worried or no?

Don't take the valve covers off. It's a 2010. Take it to the dealer.
Take it to the dealer. It's under warranty.
You have to make all the noise when you go to the dealer.
