the bolts holding the front part of the s/c case with the gears has supercharger fluid inside it (just before the intake runners). i made the mistake of opening it up and what a mess, lol. very distict smell to it. i havent sourced out the replacement fluid for it as that s/c is our welding jig for the manifolds but i imagine its going to be a pain to track down the specs on it and the amount to be used. if you happen already be in the situation i can start digging into it for you.
