I have only 400 miles on my car and on a evening drive the other night I noticed a rattling sound above 35 mph, sorta like a small rock on a can. No sound at idle or below 30-35 mph and only when it was at operating temp. Having JUST finished this car and knowing every bolt and nut, I knew there was nothing that could be rattling, so I suspected the clutch/TO bearing. Tranny is TKO 600 and clutch is a McLeod from Brent Lykins with Ford-style arm and clip-on TO bearing. I was already facing dropping the tranny because I had some slight seepage of fluid between the BH and the tranny. So, I dropped it last night and after looking around in the BH I removed the bearing and found it had spun out all its grease onto the inside of the BH. I suspect that when I re-adjusted the slave a couple weeks to take slack out of the pedal I didn't get it quite right and its been slightly touching and spinning constantly ever since. The bearing is sloppy and loose now and was clearly the source of the rattle. And it turns out my bearing retainer IS leaking just a bit on the tranny so I should kill two birds with one stone on this one.

Previously it was impossible to see given the limited room between the BH hole and frame, so I was doing it all by feel. But by looking into the BH with the slave attached to the arm I should be able to get the bearing spacing set up properly now before reinstalling the tranny. At least I know what NOT to do. Fortunately I was able to wipe out all the grease as it was in a nice 1"wide line around the inside of the BH.

Not sure if this is your problem or if the noise is similar, just thought I'd post this up.
