It looks cocked in the bore to me. But it's facing the rigth way.
If you see oil there, you should pull it and replace (don't re-use). There should be no oil present and there is no way to fix it sans pulling the engine or transmission if it leaks.
I use the older cupped plug that you hit in the center and it expands tightly to the bore. I also clean the bore with brake clean and use a little silicone around the plug after it's expanded.
