It sounds like someone here has already done it before, so maybe it's not an issue. But as thin as the oil pan is, I would think that oil contamination is going to make it leak-prone. Maybe if you could heat it up pretty hot to burn it off the back before welding? There were some guys on weldingweb.com(?) talking about welding pans a while ago and there was some discussion about the oil soaking into the steel by some minute measure and combusting during the weld to make it porous. Once you have a hole going, it gets harder and harder to close it when you can't clean properly.
I do believe that was TIG. I know MIG has a tendency to be a little more forgiving.
