So I was wondering if using oil approved ultra black RTV silicon gasket maker was ok for the differential cover. Or should I go and get a gasket from Autozone and also use RTV on it?

i only use RTV but i used the red high temp one buts thats cuz thats wht i had right next to me and i dont have any problems just put a good amount on the housing and put cover on and u should be good

wahoo

I used black with no leaks, when you use it make sure you let it sit for 10 minutes before you assemble.

I use black RTV on both my diffs, seals it beautifully. Let it set up a while before sliding the diff around on it and bolting up like said above.

Ultra black RTV will work fine, ultra copper is a red f-silicon and good for heat and chemical resistance, for the best I use "the right stuff", also by permatex, expensive but it really works in torturous (cold, hot, wet, chemical) applications.

well i use red high temp on everything including my t-case when i rebuilt it and no leaks also used it to seal up my distributor and no water gets in at all
