Sealing differential rear cover

[JohnS]

I need to seal the rear cover on a limited slip differential that I purchased.  I have a new gasket that I purchased from BMW.  I've read that most folks just seal the rear cover with RTV.  What's the best sealing option?

Just use the Gasket by itself?  RTV by itself?  Gasket and RTV?  Also what brand of RTV is recommended.  Does anyone happen to know what the bolts on the rear cover should be torqued to?  Thanks,

John

I just did this and used RTV and the gasket.  Assembled everything, left the bolts just tight enough to seat the gasket, waited an hour and then torqued to spec.  No leaks.

last time i used a gasket by itself with no RTV, its working good, no leaks.

...and I usually just use RTV.  Permatex super black.  So I guess the answer in this case is "it all works!"
