The ticking at times will sound almost normal at idle, but when I rev the RPM’s up the ticking will increase in sound. If it’s a lifter, will the sound increase with rpms going up?

So is this something I just wait for it to be consistent. It’s happened roughly 5 or 6 times since august. Is their an oil additive to try?

Thank you for the response! I forgot to mention in the first post. When the dealer had the vehicle they it was the high pressure fuel pump and vacuum pump activating. 1. If that's correct why don't I hear it more often? 2. I'm not sure if the loud noise ever produced while the dealer had the vehicle. Any thoughts if its the fuel pump or vacuum pump? Just doesn't sound like that noise would be standard in my opinion?

Truck Specifications: 2018 Silverado LTZ 6.2 Motor 27K miles Rebuilt title: interior fire damage to left passenger seat, no external damage, only passenger seat and door panel replaced. Warranty: 3RD Party warranty **I randomly get a tick/tapping sound from the passenger side of the vehicle. I've taken it to the dealer multiple times, haven't been able to reproduce it and said everything is in normal operating condition. Took it to a muffler shop looking for any issues with the manifold and was told that everything is all good. Just doesn't sound normal whatsoever, has anyone had this noise or any idea. Please let me know, not sure what to do since it doesn't do it consistently. Videos are attached. https://youtu.be/in0JBBzw574 https://youtu.be/kdfd4TFOmuI
