I have heard that before a high pitch whirring noise right at clutch engagement. It is caused by dried out or no grease on the input shaft splines. I worked at a Honda dealer in the 80s and put in hundreds of clutches because of that noise. They changed the type of grease they were using and after several thousand miles they all made noise and got replaced. Almost everyone in the shop was installing new clutch's every day.

Well then, I hope I can wait until next winter when the engine gets pulled.

If you didn't already know where it is, you need to get someone who has changed one in a C2 before to do it or assist you. It is not a quick and easy job. It requires extra work because of the limited room due to the frame crossmember location. Many pull the engine and transmission together, either way you want to do everything right the first time, so that it doesn't all have to come out again.
To be clear, it's not a continuous noise, it only happens on the way up just before releasing the clutch. After I let go of the clutch there's no more whistling chirp.

Once again, only happens on the way up just prior to releasing. I will record a uTube video on Saturday.

Hi jsans,
I agree with GGvert, the bearing will progressively make more noise but it will take some time for it to fail completely. Remember that the bearing is only working when you press the clutch pedal down, and these cars are not daily drivers, so it will last some time. If your Muncie is working fine there is no reason to mess with it other than new fluid.
Here is a tread with excellent pictures of flywheel, pressure plate, clutch disk and throwout bearing
It does sound like something needs to be greased around the clutch.

I may have misinterpreted your description. If it's a single chirp each time your clutch pedal reaches the top, you probably just have a return spring or joint in the clutch pedal that is squeaking with movement. My experience with a release bearing has been a rotating type chirp while the engine is running at the top of the return.When I read chirp or squeal, that's the way I visioned the problem. If the issue is in your clutch linkage, it should chirp without the engine running also. You may just have a dry spot, or a spring type squeak. If it's a single chirp, get under the car and have someone push the clutch and release to where the chirp is and follow the sound. Don't rule out under the dash rub somewhere like through the firewall. It would be a shame to pull the motor/trans for a squeak somewhere else.

I've had a couple of cars that did this.
One did this for a long time and I ignored it forever, and never fixed it and it never seemed to matter. That was a long, long time ago and it was a junker.
More recently, I had a 2004 Mustang GT and it started chirping when I pushed in the clutch pedal at around 35,000 miles. Drove me ape-chit but it spontaneously quit before 60,000 miles and I never did anything about it.
So that's two cars with about maybe 50,000 miles out of two or three dozen clutch cars that did it, and I never did anything to fix it, and it never mattered. But it did drive me batty.
Seriously, if it's not grinding, I would not sweat it. Just try to ignore it. That's the hard part.
