Valvetrain noise?
My 2020 LS makes a bit of a ticking noise under acceleration- starting around 2000 rpm and getting louder as engine speed increases. It’s not very loud; I’ve tried recording it with my phone and it isn’t audible. Oddly, I don’t hear anything when revving the engine in park/neutral- it only happens while in drive.
Is this normal? The LS doesn’t have an engine cover (thanks GM) so I’m just wondering if it’s a normal sound that would typically be masked by an engine cover? |

Probably the old beloved direct injection tick.

But isn’t DI tick most prevalent at idle (and not under load)?

Nope, if anything it seems to get a little louder once the engine warms up.

Yeah, the dealer claimed they couldn’t hear it, and I don’t think I can stand another 3 days in one of their loaner Equinoxes. Maybe I’ll see if the guy that changes my oil can diagnose it.

At least they didn't loan you a Trax like they do to me every time.

I know that DI engines tick loud. Wonder if it could be out of spec valvelash.
