As I and Sansho said about, shop around and replace it. Remember when tightening, you're compressing a rubber VCG and a rubber grommet, if you tighten one side until torqued that'd side will become much tighter when the opposing side is torqued. Start from the middle and tighten one nut 1/2 turn, then the opposing nut 1/2 turn alternating between the two. Once those two are torqued, tighten the remaining nuts in an outward winding spiral, you want those pressures to be expelled to the outermost edge of the VC.
