2018 Silverado LT 5.3 cold start idle tick

[VinceS]

 start up idle tick. it goes away after I drive or let it warm up for like 30 mins

i have almost 14000 miles and the sound keeps getting louder 

im planning on taking it to the dealer ship just want to know if any one else has this sound 

I’ve tried different grades of gas but it didn’t make a difference. 

check out my you tube video

That engine has always done that, from 2014 until now. It's normal.

My 2016 5.3 with 55k on it does it also.

What you are hearing is the normal expansion process of internal and or external exhaust parts that are simply heating up.

You get the same noises in reverse when the truck is parked and turned off as components cool down.

Completely normal.
