Changed mine a few years back and there was a rubber-type seal in there. I replaced it with a FelPro rubber-type. Dropping the pan is fairly basic. Remove the cap and remove pry out the bottom half of the seal. The top half can be pushed thru if it is a rubber-type. Once the end protruds grip it with needle nose pliers and pull it out. Be careful with scratching anything. If you are lucky you can get by without loosening the other caps and dropping the crank a small amount.
When you put the seal in try to stagger the joint so that it is not in line with the mating surfaces of the cap and block. In other words put the ends of the seal at a 2 o'clock and 8 o'clock position. This will help keep oil from leaking past at the block/cap joint.
