Had the same thing happen to me when I put my locker in. Two things cured it:
1.) After laying down a good thick bead of RTV Black, I tightened down the
bolts evenly but only hand tight/enough to hold it on and make contact all the
way around.
2.) I waited an hour after hand tightening to let the RTV set real good before
gently snugging them into place and filled her up with gear lube.
Hasn't leaked or even weaped a bit since.
Luck!

Subject: DML: Leaking rear diff cover

Have small problem(but an annoying one) which I would like some help on. I
initially took both front and rear diff covers off back in March to change
the gear fluid. I had a problem with the rear diff cover leaking maybe a
month afterwards, so I drained/reused the fluid and resealed the diff cover.
Well I pulled the diff cover off about a month ago, cause I thought my rear
LSD went out, so once again I put everything back in a resealed the diff
cover. This seal is now leaking again, grrrrr. I dont care about having to
take it back off, resealing it, and adding new gear fluid; it is just the
fact the it shouldnt be leaking! The front hasnt leaked since the first time
I pulled the diff cover and sealed it up! I didnt do anything different on
the front diff either. What the heck can I do this time to hopefully ensure
a leakproof seal?? I do fully clean for the diff housing and the diff cover
to remove all the old RTV and I am sure to use plenty of brake cleaner to
completely dry things out for a good bonding surface. I have used RTV Ultra
Blue and Ultra Black, both leaked. I want to do this one last time and not
worry about it until next diff fluid change. Would using a diff cover gasket
meant for a Chrysler 8.25" rear end work better??? I have also read not to
tighten the diff cover bolts down all the way, cause the RTV gets thinned
out too much, but I tightened the front diff cover down pretty good. Like I
said, I want to fix this rather annoying and simply(supposedly!) leak and do
it right so I have one less thing to think/worry about. THANKS!
