Clicking noise with new Spec Clutch.

[Modern Angel]

So, like the title says I just had a new Spec Stage 1 clutch kit put into my '93 240 with a KA engine/tranny. A day or two after getting it in I noticed a clicking/ticking type noise when I put the car in neutral. It almost sounds like the sound that semis make when idling. Anyway, when I push in my clutch the noise goes away. So, I'm thinking that the shop I went to must've screwed something up with the new throw-out bearing install. So I went back to the shop and had my mechanic take a listen to it. He seemed quite sure that everything was fine and told me it's just the TO bearing knocking against the splines of the pressure plate and that it would go away eventually after it gets "worn in".

I dunno about that since I'm at about 350 or so miles on the new clutch kit and the noise hasn't gone away. So I'm wondering if anyone else with one of these kits has experienced this noise also when it was new or if I should still be worried.
