Loud ticking noise
Hey everyone. I have a 2016 Z51 manual with about 20k miles on it. I'm noticing a new "ticking" noise coming from the engine bay (I think) right after starting the car. Attached is a recording from the driver's seat with the doors open.
Few things to note:
1. It's loudest right after starting the car, even if I've already driven a bunch that day. A few minutes into each drive, it's either much quieter or completely gone.
2. It's very intermittent. Maybe only 1 out of 5 starts.
3. It seems to be in sync with the revs; i.e. the frequency of ticks increases with revs.
Any thoughts are much appreciated!

It must be the electric car next to you, lol!
Seriously I would check your oil level.

I would agree with the others. That does not sound like a lifter or an exhaust manifold leak. Sounds like the belt tensioner or a failing belt itself. Good news is both are pretty easy to replace.
