I was cleaning the area for the intake gaskets and I remembered that someone told me to replace the oil pressure gauge while I have easy access to it. I was trying to figure out how to detach it from the thing I'm looking to replace but it broke.
I took the whole thing out and tried to unscrew it from the thing that I'm looking to replace and it's just stuck.

The think that I'm looking for is what it's screwed into. I want to replace it because I'm not sure if I can get the broken oil pressure gauge out and it's a bit scratched up. I'll post a picture if you guys need it. It's late. If you need anymore info I'll try my best to provide it.
