long story short, I've got a stripped oil pan. Would it be best, to try and repair, like drilling and tapping a bigger diameter hole? Or will I need to replace oil pan ?

I tried a plastic expanding plug replacement to buy me a little time after my last oil change when I noticed I couldn't tighten the bolt due it probably being cross threaded last. and it didn't last very long, maybe 100 miles before I noticed my van running extremely rough and loud clattering sound while goin down the road. I peeled off as fast as I could and as I investigated I found no plug in sight, and probably left several quarts of new oil down the past couple miles of freeway. I hope I no serious damage occurred else where....

thanks for the help.
