Engine Noise? (video included)

Just noticed this sound coming from the engine. When the engine is cold (initial startup) the sound is louder just like in the video but as the engine warms up the sound is more quiet. Seems like the sound comes around the intake areas. Any ideas? Is this normal? Thank you!

Have you checked the oil leave?

Hard to tell on the video could be a lifter but with such low millage I would not think that would be it.

Yes, definitely sounds like at least one valve operating close to max tolerance gap and since it quiets on warm up is indication that it comes into tolerance at temp. Suggest you do as said above and if that doesn't cure, then get it to a mechanic before you have a really big bill to pay.
