Default is my gearbox/clutch making funny sounds???

my car is making a whining sound (like i can hear the gears or clutch??). It only happens when i let off the throtle. It does not make the sound when i accelerate or idle. I have a busted manifold gasket and i have new clutch springs. (i found the proper gasket after some looking and will pick it up tomorrow) I thought my gear mesh was to tight but i loosened up a bit and it still makes the sound. It is hard to describe the sound almost like the flywheel on the starter box when it's winding up. My guess is it's the sound of the engine (bad muffler gasket) when it's winding down from high rpm without the sound of increased combustion to mask the sound of the leaking manifold gasket. Or i might have a leaking diff??? but the gears move fine. any ideas?? how can i tell if it's one of my differentials???? could it be the new clutch springs?? But i can't remember if it did it with the old springs.
