OK so I just came back from Chevy and observed with the foreman of the service department we listened to this video first and my car second, again, at cold start. He told me it is the oil pump sucking the oil up through the oil pump mechanism and it's the sound of the pressure of the oil going through the pump so it could feed the engine and its normal. The reason why it doesn't make this sound after cold start is because it drained out of the oil pump mechanism. Fluid pressure racing through channels to destination. I'm not totally convinced that this is normal. Especially when you hear other people saying it's the starter, or it's the fuel injectors, etc. He said the old car pumps were submerged in the oil pan and the new ones are not that's why they make a noise. Don't know why they changed the engineering. It is a ridiculous sound, it sounds like metal to metal. If anybody has a difference of opinion, a more technical response to this freaking noise, please post.

I am no engineer but having an oil pump not submerged in the oil reservoir just sounds like a horrible idea. Maybe that's why my 2018 had metal shavings in several oil changes. I drive this truck like my grandmother most of the time and I still get tiny pieces of metal shavings in my oil when I change it. Definitely not a fan of modern engineering between the stupid 8 cylinder pretending to be a 4 cylinder half the time while I'm driving and all the other weird engineering signs makes me miss my 1984 K20

It’s normal, the high pressure fuel pump for the direct injection is mechanical, when the truck sits a while the pressure leaks back the sound you hear is the pump rapidly building pressure again. You can still hear the pump as a tick while the engine runs warm.

Mine does the same exact thing, always from a cold start! I was reading some online forums, and they are saying this is a normal sound, and has to do with the DI fuel injection system. Nevertheless it bothers me to, I'm doing a oil change this weekend and adding Lucas oil additive, not sure if it will help at all, but I'll feel better knowing I'm taking a extra precaution for wear protection. Good luck!
