I've owned and been around many direct injection cars, including newer Lexus's which have insanely loud direct injection, I know what DI sounds like on the new LT1, and this is not that. This noise is only coming from the driver side bank (sounds like the head). In person it is much more prominent, but you can definitely hear it towards the end of the video here where it actually starts to rattle at ~2k RPM. Sounds like lifter tick to me.
BONE STOCK (other than a Mishimoto catch can), 25,400 miles, M6, 2016. I heard this noise slightly when I picked the car up at 23,500 miles, but it is much louder now. Oil changes only at the dealer.
Am I crazy? Is this normal?
If anyone has any insight or knowledge about this possible issue, your response is much appreciated. Thanks in advance.
Just scheduled an appointment with my local Chevy dealer on Monday to see what they say. Know one of the advisors there, hopefully he takes care of me. Will post with updates.
