Do I need a special socket or something, also my car is 93z so the oil sending unit is by the oil filter. Thanks

 

You shouldn't need anything special to change that sender. You may want to consider removing the oil filter for clearance although it isn't completely necessary.

 

thanks Chris I was just wandering because I heard of guys going and buying sockets at auto zone just to change the oil sending unit.

 

Yours is more accessible than the later years, so you might not need the special sensor socket. A deep 6 point socket might work on it, but a 12 point won't. The sensor has special rounded shoulders (that is why the special socket can be needed).
