Im sorry, just trying to get a crankshaft sensor out and the top broke, i am trying to do this myself, first time ever working on a car, i have no help, there is a o ring on this part, im guessing its baked on or swollen on, my searches resulted in drilling a hole, but my mind is telling me to try to chemically get rid of the o ring so it will pop out, there is no threads on this part
