Suggestion
I don't think anyone would do a clutch without replacing the TOB, so it really will not cost you any extra.

Test your clutch by going from 3rd to 5th...watch the rpms.

Suggestion
Unusual mechanical sound could be the throw-bearing failing, only in use during de-clutching/declutched.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hey folks,
I've felt my clutch pedal getting a bit stiff lately so I figured I'd need a new clutch (I have about 73K miles on my C4S).
Yesterday when I depressed the clutch pedal in any gear I hear this high pitched loud mechanical whirling sound, the sound goes away as soon as I engage the clutch.
Is this normal for a clutch that's past its time, or am I looking at a different issues here?
Any help would be great, thanks!

The throwout bearing seems to be the concensus.
Pelican has a kit:

996-116-911-02-M38
Our 3-piece package includes all original equipment Sachs or OE Porsche clutch components. Contains New Pressure Plate, New Clutch Disc, and New Throw-out Bearing.
Looks like that's my ticket...$587.50
Thanks all for pointing me in the right direction.
Actually, the clutch job is probably 8 hrs, and you'd normally put in a new release bearing at the same time. If you're going to do one, might as well do the other. Probably time to check out the rear main seal, too.
well thats 'by the book'. i remember the dealer giving me the old 'oooohhhh its a really big job and you will save 8hrs of labor if you put a clutch in at this point....'
as i understand it (and im certainly no expert) the fix itself isnt that tricky but theres a LOT of taking out and putting back to be done=time
As with most 'by the book' numbers i'm sure it actually takes a lot less but anyway it is certainly a biggie......
I don't think anyone would do a clutch without replacing the TOB, so it really will not cost you any extra. You got pretty good mileage out of that original clutch!
I remember in the first P-car I had, (89' turbo 930), just the parts alone were over $1100 for the clutch! Yuck.
