Default Cold start tapping?!

Noticed this morning on my 2019 with 7k miles. Has me concerned it’s a lifter but it goes away when warmed up and the tapping is quite random, like every few seconds it will tap tap and then nothing for a bit. Followed by maybe a singular tap. Attached is a video I found which is exactly what I’m experiencing. Hoping it’s just normal cold start stuff that I may have not noticed early on.

I could not tell that anything was wrong with the engine, but if it is a new noise to you, you probably should take the car either to a dealer (if a warranty exists) or a good independent shop that has a strong knowledge of the Corvette. Hopefully it is not something wrong with the engine.

Well for what it’s worth I think you made me feel okay.. The car is new to me, I only have about 1500miles of seat time and I tend to be hyper focused on sounds. Watched videos of dropped lifters and can tell it is very apparent when that happens.

That engine sounds completely normal to me. The injectors and high pressure fuel pump makes those sounds. Sounds good.
