I have a 1987 740 with 215,000 Miles. My Oil Pressure Sensor is leaking oil. I can see where it is coming from. I am sure it is 16 years old like my car. I may have accidentally damaged it when during my last oil change I had to use a pry bar and a two pound hammer to knock off a frozen oil filter. (This was my first such experience in forty years of self oil changes.) Regardless, I can not see exactly where the lead is at or if there is any damage I inflicted. That background aside, here is my question:

I have heard that Volvo oil sensors may break off in trying to remove them. I now am concerned that this may happen to me. Anyone experience or hear of this before. I hate to think about drilling out the remnants and retapping if this happens. There doesn't seem to be much room to work there. Any knowledge or tips would be appreciated.
