2 words F ZZP, get one off ebay, they are going for 20 bucks there vs 40 at zzpoop.
get 2 bottles of GM supercharger oil, from the dealer.
drain the snout first, ( some plugs are a t-35 and others have a Allen key) you can use a old spray bottle, stick the tube in the hole there, and spray it into the spray bottle, to empty it.
i'd wear some latex gloves too, the old oil stinks like hell, and dont wash off so good.
i laid some rags down too, under it to catch what you cant pump out.
and a can of brake cleaner to clean up the inside of the snout, and the case side.
and i cant remember the stuff is called to seal the snout back up, i used high heat black rtv, but others will say to use the right stuff. mines been holding for over a year now, so its up to you. witch ever you use, use just a smear of it, you dont want it oozing all over the place, a little goes a long way.
