Clutch/ZF6 question
When my clutch is released and the transmission is in nuetral, there's a noticeable "gnashing" noise, and when the clutch is engaged the noise stops. This has occurred for some time now, without getting worse. Is this normal?

I disagree. The noise in mine is definitly not the flywheel. It did it from new. I replaced the clutch a couple of years ago and checked the flywheel at that time. It's perfect. I know the "rocks in the can" sound you're referring to. We're not talking about that sound. The closest thing I can compare it to is the sound a supercharger makes.
