Strange transmission noise??

[gingerbredman]

hey guys i hope yall can help me out here. well, its been doing this a long time, pretty much since i got the car about a year ago. well, when i first crank it up and its cold, i have my foot on the clutch and in 1st gear right? well i let the clutch out and it makes this...very strange noise,.. like a " wha wha wha wha" low pitch noise but only it warms up a bit. i dont think its the clutch, ive only had to replace the slave cylinder and it works fine, im thinking it may be bad pressure plate or flywheel i just hope its nothing major, well if anybody can help me out it would be much appreciated, thanx

It's the pilot bushing,The nissan replacement looks like pressed particles and the O.E.M piece looks like a machined piece of brass. Use the ugly replacement.
