[C5David]

Occasionally I'll have a passenger that requires me to drive my Z06 like it's missing 4 cylinders. You know, like your grand mother? Anyway, I've noticed that when I drive like this, and I'm crusing at 65 in sixth gear, my engine makes a funny irratic ticking sound. I hear the noise coming from up front. Has anyone else noticed this?

David, I have only had my C5 in 6th gear twice, I cruise on the highway in 5th.

If I recall, at 65 in 6th the mighty LS6 is turning about 2KRPM. Around this engine speed there is a "normal" valvetrain ticking noise. My only guess. I can hear it on mine occasionally.
