So! my l67 has the stone breather on the end of pulley nut. I noticed the pulley "weeping" around the nut. Its def supercharger oil but, if it was the snout seal wouldn't it leak out from behind the pulley? on the face of the snout? I have a slight drip that runs down every few hours from around the nut. Now thinking it could be the breather plug but man oh man I have no idea... the pulley was never removed before and the nut was never cracked... any ideas?
