Is my clutch gone?

[donv]

I think we need some more info to really help here.

The clutch will produce some odor if driven really hard. This has happened to me before with no lasting result. Were you doing repeated hole shots or doghnuts or similar really abusive acts? If not, it should not be a issue with the clutch material glazing up. Regular "spritied" driving should not cause a problem.

I presume you didn't hear any sound of breaking parts or you would have said so...

You say you could shift, but do you have anything that indicates the transmission is really changing gears, ie: other than just where you put the shift lever? (for instance, you could have an issue with the shift cables/linkages and not the clutch?)

Unless something caused the clutch actuator to jam or bind in the "pedal depressed" equivalent position, the clutch should be stuck with the transmission engaged if the slave failed.

Even a glazed clutch should provide some engagement feel. You could try putting the car in 1st gear and try rocking it back and forth by hand to see if you get the feeling of the transmission being there.

I can't remember the details of the Boxster tranny and clutch mechanisms at the engine, but you should be able to see if the clutch and/or shifter is actuating items on that end with someone working them in the driver's seat.

Knowing some of these answers should help you narrow down what is really happening... hopefully it is something less drastic than clutch disc failure!
