Weird clutch related noise

    I just got my RX8 back from an engine rebuild and now there's a strange clutch related noise. The guys said that if it doesn't go away in a few days to bring it back and they'll take a look, but in the meantime I'm really curious to know what it could be.

    So the noise is a kind of chattery/knocking/grinding noise and it happens when I'm letting the clutch back up, i.e. when taking off from stationary (forward or reverse) or changing down a gear. It's only barely audible on take-off, but when changing down it's really loud and horrible as the engine brakes. It's not really noticeable when changing up gears and it doesn't happen when stationary (clutch depressed or not).

    Here's a couple of videos. Sound quality isn't great but if you turn it up loud with earphones then the noise can be heard.

    Just for the record, it was the pilot bearing. Seems like it took a knock when the engine and gearbox were being mated back together.
