If you loosen the Pan there is no gasket just sealant on it so if you cannot re-seal it you could end up with a leak somewhere else.
Also, in theory ounce the Pan is loose you are supposed to align it with a Special Tool before you tighten it.

Truthfully. I don't think there is any type of sealant or glue from the factory. Just a highly machined fit. But IMHO once you disturb it, you'll need to seal it.

I just aligned by sight.
