And if you are replacing that seal you will need the gasket that goes between the crankcase and the cam and crank cover plate and don’t forget a new serpentine belt since you went to the trouble to remove the old one just to get to where you were going.
The crank position sensor is on the outside of the crankcase, front side, engine lower left (right if you are facing the engine). No need to touch the cambelt or the cam case cover.
