Strange Noise
First off, I have an 02 mn6 with 11k on it. I was stopped at a light the other night, I took my foot off the clutch and took the car out of gear. Then I hear this strange noise, kind of a quick clack, clack, clack. I thought it was the guy next to me. I turned the radio off and listened more, it was coming from my car. I pushed in the clutch and that made the sound more quiet. I have no idea what the noise was.
I only drive her on the weekends. Any ideas???
Thanks

Normal noise on MN6.
Drivetrain rattling
The valvetrain makes a significant amount of noise at idle. It may sound like sewing machine. Converting the valve rockers to true shaft-mounted adjustable roller rockers with may help eliminate the valvetrain noise if adjusted properly. Installing a big cam and stiffer valve springs will make the noise louder.
On manual transmission cars (M6 or M12), the transmission sounds like it is rattling when leaving the line. It is normal. It is the clutch throwout bearing rattling around. Sometimes you'll hear a horrible rattle if you shut off the engine. If you press the clutch pedal in while shutting off the car, you won't hear it.

Yep, its normal. My 04 does the same thing. Don't be shocked the first
time you shut it off with clutch out in neutral, makes a good racket then
too. I always shut her down with the clutch the in.
