2024 Buick Envision — ticking noise follows RPM but fades when warm

There is a light ticking sound that follows engine speed for the first few minutes and then becomes hard to hear. Oil level is correct. How would you separate normal injector noise from valvetrain noise?

If it were in my driveway, two 2024 Buick Envisions can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. That's the sequence I'd use. No warning lights, which is why I'm documenting it.

It did ticking noise follows rpm but fades when twice this week, both times after sitting. No change in mileage feel. Happens in gear, not in park, for what that's worth.

Intermittent stuff lies if you only catch it once. A pressure test beats staring at a dry driveway if the 2024 Buick Envision is losing coolant with no puddle. Save the big job until that test fails. On “ticking noise follows rpm but fades when,” that was the fork that mattered for me. This is from a 2024 Buick Envision in Texas. That's the sequence I'd use. This is the filter I use when the thread starts repeating itself. I already checked the easy fluid levels.

I wouldn't throw parts yet. If a shop can't duplicate it on the 2024 Buick Envision, bring a video plus freeze-frame data, not just a story. Save the big job until that test fails. I'd want that in writing, not as a promise. Your commute and mine probably aren't the same, but the test still applies. If this is nothing, great. I want that in data.
