open up the noid body and make sure the oring in there isn't pinched/damaged or anything.
Are you sure the "venting" is coming out of the noid?
I'd break into that and clean it up, if that doesn't solve it then I don't know what to tell ya.
Honesty and Integrity are the basis of a true man. You cannot have one and expect the other. Both must be earned and fought for. It is not easy, nor should it be. I will not be tempted into making the easy decisions over the right ones
