diff cover sealing

[thedanielm]

anyone have any trouble getting the differential cover to seal properly?? im having a heck of a time. I covered it in coper coat sealant, it leaked, i took it off cleaned it up and gooped even more of that stuff on. this is really starting to get on my nerves. I made myself a thick rubberized cork gasket now and hopefully that works. only thing im worried about is maybe there is a crack in the transmission or something

anyone know any tricks to gettin that thing to seal?

clean both surfaces with brake cleaner then use a 1/8" bead of Ultra black sealer... this is the BEST stuff for that application.
