Well, I've been closing in on finishing alot of work on my 92 f150 and noticed a crack in the t-case where the drain plug screws in. I assume someone tightened it to much in the past. Can this be repaired? It's fine otherwise. Tony

 

I have the same crack by the plug on my 92 which leaks a little, I just cleaned any oil residue off and applied some silicone gasket maker to it.
