I assume that when you say idle, you mean in nuetral. If this is true, 
then the noise, I would think, isn't coming from the engine. You need to 
look at the work you did at the clutch and rearward. I don't think, based 
on what you have said, that the problem is even in the clutch area, as 
the position of the throwout bearing and such should be the same in 
neutral or in gear. The noise must come from a part that is turning when 
in gear and not turning when in neutral.

Irrelevant to the problem, I think.
