Jaime:
I took the car to a local shop called ASG here in Northern Va. They, along with IMA Motorsports have the best reputations in the area. They recommended basically doing a complete clutch overhaul, so I let them do it (new sleeve, new crank seal, new pilot bearings, etc. etc.). One thing they didn't replace was the slave cylinder, but it was something they seemed to be implying I should do but didn't.
Right after I picked up the car, we had a snow storm with about 30 inches of snow, so the car won't be on the road until all the salt has been washed away...hopefully in a week or two.

Ok, so let's say I'm on a trip and going through West Cupcake, Ohio I hear these sounds. How long can I drive like this? It seems like the car would be driveable (few hundred highway miles), enough to get home. Any opinions?

MSchett2:
When ASG pulled the flywheel, I wanted to see it and photographed it (it will eventually end up on my web site but it's not there yet).
In any case, while photographing it the guy working on it demo'd the difference between my old, shot flywheel and the new one. The dual mass flywheel is, as the name implies, two masses. The masses move with respect to one another. The difference is that the good DMF is VERY hard to move one mass with respect to the other because the damping stuff is entact, but on my old, shot flywheel I could actually move the second mass freely with a single hand, and swing it to it's motion range limits which would, if done fairly quickly, produce a "clack" sound.
The guy who worked on the car didn't seem to be too alarmed about the idea of me driving the car, as long as I didn't drive it much. Because of what I described in the preceding paragraph, I would think that as long as you take it easy, meaning GENTLE acceleration, no sudden starts and stops, and avoid putting your foot on and off the gas pedal in any rapid manner, you could PROBABLY make it home, but if you allow the problem to go on too long, you can end up doing some major damage to other parts of the drivetrane.
You might want to check with your mechanic to get his opinion. After all he's probably seen it before.
