When I got my car I turned the plug the wrong way when I was changing the oil and didn't think anything of it but not there are no threads in the oil pan and it leaks, what should I do?

I've done that, they make a "one size over" plug that will cut new threads when you install it...check local parts store like Autozone, or Napa, they should have one
Check with your local auto parts store. They used to sell oversized plugs just for that dilemma.
You have go to the local auto parts store and get a self tapping oversized drain plug for your oil pan, be very careful, if you get too large of size it will be too hard to thread, and make sure you start it straight and not at an angle or it will not seal, you will lose your oil doing this, so get some new oil before you start. And if you have never cut threads before, you turn clockwise to start cutting, then when it starts getting tight or snug, back it out (counter-clockwise) about a 1/4 to 1/2 turn, then continue cutting the new threads (clockwise), until you have to back it up again, repeat until you are done, then try and collect the metal shavings a magnet will help, some of the drain plugs have a magnet built in. Good Luck.

Sometimes when you are sideways or upside down, its hard to tell what way you should turn....so i remember what i heard about 10 yrs ago... righty-tighty & lefty-loosy. Has helped out alot. Ken :yup:
options for the oil plug are to get a new pan or braze/weld the plughole and then drill and tap for the standard size pan plug.
They also have an expanding rubber oil pan plug that's sold at the auto parts stores for around $5. It's a rubber grommet around a screw that expands as you screw it in, sealing the hole. Kind of like a drywall anchor. You won't have to worry about threading it right or not, it will expand into any size hole until it's sealed.
