I was doing an oil change since I am scheduled for an autocross for the weekend and I noticed that the "T" fitting installed on my oil pressure sender port was starting to leak.

As I loosened that up, the fitting connected to the port on the block took off a little bit of material and threads from the port with it. Now it wont thread back in for me to reinstall the "T" fitting since it wont thread in and I cant close that port for me to refill the car with oil.

What I am asking is, how can I fix this? What options do I have? If anyone can help that would be really appreciated because I really need the car back before Saturday since I am scheduled for two event days.
