. Got this after dealer did oil change. Don't know if one has to do with another but only noticed this after oil change. If I start up car from being cold, the intermittent knock tick happens after a minute or so of being started. It them continues here and there until car is fully warm. I've driven the car hard since and it sings as usual at high rpm. Noise also doesn't get worse from what I hear as I raise rpm. I'm baffled.

Any ideas from anyone on here? Thanks!

It's A sort of clicking sound.Don't sound like rods or valves.Well not to me.Maybe exhaust sound,I mean maybe something lose.Only guessing.

I remember a similar issue with the Camaro ZL1. There was a "type writer" click sound after some oil changes. My understanding was that it had something to do with air in the oil working its way through and with the extremely tight internal tolerences on engines now it can happen. My zl1 experienced the same thing but it eventually went away. My Stingray engine does display some initial noise / ticking when it is first started but goes away after a few seconds of idle when I gas it a bit. sorry probably not much help here.

That sounds like metal expansion noises from the exhaust as it warms up, which would explain why it goes away when the car is warm and why RPM doesn't change it.
