No....Spin the pulley back and forth and listen for noise...IF you hear some rattling/clunkin noise than it'* the coupler.....Which is probably not a bad idea to replace anyways for good measure...I gotta do mine soon when I get the money for gaskets.

I didnt hear any noise at all. I am now wondering if the gasket around the */c is bad because of the fluid that you see on the pic.

You may have a leaking snout seal, CR-7965 or one of the two mating surfaces between the snout and the supercharger housing. My seal leaks a bit. There is a way to put on a new seal without taking off the whole supercharger, but I haven't been able to get the new seal back on properly without ripping it. I think you need a seal installer.

Steve, why is this in 92-99 instead of forced induction? Moving it for you. For detailed instructions on troubleshooting this and fixing it, try the search function.

You've seen this dozens of times at least.
