Is this a normal engine noise?

[Rodolfo Garcia]

How’s it going guys, i recently purchased a pre owned 2017 lt 5.3 v8 silverado with 35k miles on it. And i was just wondering if this is a normal noise the engine should be making. To me it sounds somewhat like chirping, cricket noises, or something of that nature. Maybe its normal and i’m just thinking there’s something bad because i bought pre owned. I attached a video. Thank  guys and also i absolutely love the truck. I have noticed there’s more pep in the driving when i fuel with 89 gas instead of the other 2. What do you guys think about that?

I hear DI noise

Yeah, just sounds like the injectors/lifters. The direct injected engines are loud.

Direct injection. Type of fuel injection.

The video you posted will not work for me so I can not comment on it. However direct injection engines are more "ticky" than previous engines.

pretty  much normal, iv noticed if i run a better octane fuel(91or93)  the noise your hearing seems to quit down alot.
