If you are desperate you can try, but you'd have to get the area very VERY clean, with a solvent and then let the JB set overnight. I'm concerned that the vibration will defeat the JB weld however. It's really not meant for this sort of application. Whatever you do don't smear it over a bolt.

The proper way to stop that leak would be to replace the oil pan gasket. However, I realize that may be more expensive than you can afford. If you want to seal it up with chemicals, JB Weld would work; but it also might bond the oil pan to the engine block, which could result in problems later on. My preference in a situation like this would be to use Permatex Grey RTV Silicone gasket sealer. The Grey formula is more rigid than the other types, and will seal better. Run a Q-tip into the area first, to clean the surface as much as possible.

I hope this helps!!!
