None of us know the location of the leak.... but if it is drain plug related some third parties make a replacement drain plug the fixes the original thread with a replacement and adds a new inner drain plug. This facilitates never having to use the original threads from the pan and supposedly allows for quicker oil draining (not flow but opening and closing of drain). Simply put- if the drain plug/ thread is the issue a third party quick drain plug may be an inexpensive fix. It may allow you to secure a device into original threads (with some teflon type help) and still allow for oil changing without stressing the pan threads.
