do you mean the sensor with housing? Is it the oil pressure sensor or something similar?... that is unscrewed and once loose I screw it back on. I am going to open the motor where it is, it is more comfortable for me (although it looks more shabby)... right now I wonder. Is it necessary to remove the studs that "hold" the cylinders etc? to open the case? I have unscrewed everything and I can not loosen the casing to open. Thank you very much for the advice.
**So far all the screws have come out easily....

ummm... the crankshaft is broken.
