Taking the noid apart rarely ever makes it better. The SMC's don't like to be fondled much lol.
That being said........get a bottle of water with a tiny bit of dish soap in it. Then spray around the noid. You'll see where the leak is very specifically because bubbles or spray will form in that area. If it's on the noid......you'll need a new one most likely.
Other than that, make sure you noid is screwed on level and with even pressure on both screws. If it's on lob-sided it will leak out the gasket.
