Did anyone find out what this sound was? My 2001 Vette has started making this sound.

Sounds just like my ls1. I'm starting to think there is no such thing as a quiet ls1. At least the sound goes away when it's warm.

I have that same noise around 1200 - 1400 rpm, it doesn't seem to hurt anything but I would really love to know what it is

I hear a chirping noise just after the rev, is this what you're talking about? If you are facing the engine, does it sound more like it comes from the left side? The upper pulley on my 98 makes the occasional noise, I spray lube on it and it goes away. Could be something like this?

Normal according to ls1tech. Although one guy said his was making a similar sound due to a loose coil on one of the spark plugs. I checked all of my coils and the sound is still there but its been running strong.

It’s a lifter

Paul Pasquarella I don’t think it is. I have this exact noise and it was there when my motor was bone stock. Did a cam and new lifters and the sound never went away. Checked all the stock lifters and no damage to any of them. If it were a lifter mine should have went away when I redid the valvetrain
