8 3/4 Rearend

I hate using sealant of any kind, with or without a gasket. Since my car is a race car it comes apart more frequently and I hate cleaning sealant off. Plain gaskets are much easier to work with. Now having said that I just put a fresh gear in my 8.75 and used only a gasket. Well it's leaking and I need to take it back apart. I don't know if I tore the gasket or something else is wrong but I doubt I'll use any sealant on it when I put back together unless I just can't find a reason for why it is leaking.
