2011 V6 Camaro LT Clicking sound? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I hear a very loud ticking sound that comes from what seems like the back side of the engine on the passenger side. I've captured it in the video below, you can hear it pretty distinctly. I've read about all kinds of ticking noises that come from these DI engines and the lifters and such, but someone elses input on it would help make me less worried about it, unless I need to be worried.

It's a 2011 V6 LT RS. The noise does get faster with higher RPM, but isn't always there either, it comes and goes.

The clicking sound is the fuel injectors pulsing on and off under higher fuel pressures.
When the engine warm-up is completed, the high pressure fuel pump will continue to tick at a lower rate of approximately one tick per second during idle.
This is normal operation of the high pressure fuel pump and injectors.
