Belt Noise
Around six or so months ago I went and re-did all of my belt system with a new P/S Pump, W/P, Alternator, dress-up-kit, the whole shebang.
Only issue is, the constant whine it makes hasn't subsided and its been driving me crazy these past few days now that ive been starting to drive it more.
Could I get a second opinion on this noise?

I'm thinking all I have to do is tear off the pulleys and repack the bearings in the accessories with grease, but better to run it through the 'wise and knowledgeable sages of the forums' first, thanks.

Re: Belt Noise
The bearings in your accessories are all going to be a sealed design, non-serviceable. I would pull the alternator belt restart and see if the noise goes away. Or, stethoscopes are cheap. Use the stethoscope to isolate which bearing it is it's making noise and replace that accessory

Re: Belt Noise
I was really hoping that wasn't the case but it makes sense, tonight ill go through and isolate the noise.

Re: Belt Noise
I feel so stupid man...
Used the old screwdriver trick (ill get a stethoscope sooner or later) and heard bearings noise from the alternator, so I take off the belt and the noise is gone.
Turns out, the reason it has bearing noise is because its misaligned with the Crank and W/P pulley because the dress-up-kit Alternator bracket pushes it backwards at an angle and I only just now noticed it...

Re-bent and readjusted the bracket and alternator and I can hear my engine again, I appreciate your time though man, sorry to waste it.

Re: Belt Noise
Never a waste, especially when the solution is found! Glad it was relatively simple. Thanks for the update
