Hello all, I just did a oil change on my silverado. It has 24500 miles on it. It gets a oil change every 3.5k miles. I noticed a new "ticking" noise that doesn't have a pattern to it. It seems to happen randomly. Towards the end of the video you can hear it tick twice back to back. Anyone have any ideas as to what this is?

Changed the oil filter + plug gasket

Oil (mobil 1 0-20 dexos)

Cabin air filter

Engine air filter

All AC delco except for the oil.

Thank you in advance!!
