2018 silverado 1500 5.3 L v8 cold start noise

[Jwiggs152]

So anytime my truck sits for more than a few hours I get this noise on start up. Generally last about 20 seconds and then it goes away. No issues in performance or anything other than this sound. I thought it might be drain back because carmax put a garbage filter on it with no check valve. Ive had the truck just over 3 months put less than 3k miles on it currently sitting around 47250 miles. I changed out the oil and filter and it still makes the noise. Does anyone have any ideas. It is the 5.3 l v8 . Here is a video of the noise.

Welcome to the site.

 

I take it you bought it from Carmax? You should still have a remainder of the powertrain warranty left, take it to a Chevy dealer and get it checked out. 

Does not sound normal for any year. Probably a collapsed lifter.

Yes, definitely a lifter, fairly common.
