dhermesc,
I had this problem on a Ford 302 engine in a van. The self-tapping drain plug did not work.
Turned out that the tab that is spot-welded to the inside of the oil pan, was cracked. This is the threaded part that the drain plug screws into.
The only cheap fix was to weld a threaded fitting to the bottom of the pan, and use a plug to fit that fitting. I used a 110 volt flux-cored wire feed welder to do that; I did not remove the oil pan.
If this is what you might end up doing, be very careful. I had a bottle of CO2 that I purged the engine with first, and during the whole welding process.
If you don't do something like this, you could blow out every gasket/seal in the engine. It worked fine, and still does not leak.
The oil pan is very thin, so do very short welds. ........... and this welding is all done in the overhead position, so maybe practice on something similar first, if you are not a welder by trade.
I could not find a good picture to show this tab in the oil pan that cracked, but this one will have to do. Good luck.
