I have a oil leak comming from what I believe is a oil sensor that is in the front of my oil pan on my 04 saab 9-3. The problem I am having is I can't get the leak to stop, I can push the sensor in and pull it out but it wont come all the way out. I'm guessing after I took the C clamp off it would turn and lock in but it does not. So does anyone know of a way to fix this problem. I can't even find a new one anywhere...any help is greatly appreciated.
