No, there is no additive to fix this.
Yes, you can do it w/o taking off whole supercharger, however, you have more chance of getting sc oil on engine parts because even if you drain sc oil some will probably still remain in nose cone and as soon as you break those bolts loose it will leak out. Just make sure you drain as much oil as poss then have a heavy duty towel under nosecone area upon dissambly. Those bolts are pretty tight if your torqued them properly. By the way when you did the procedure how tight did you make the nosecone bolts because they are supposed to be 20ft/ lbs. which translates to 240 in/ lbs depending on the type of torque wrench you use. This may be the problem. If not and you have to go through with the whole process I used the RTV hi temp red silicone gasket maker bu "Permatex" local parts store. The manufacture recommends "Loctite #510".
