same truck new problem

Ok i have a 91 xlt and the power steering was making funny noises and i put some power steering fluid in it and over filled it, not over the top of the tube but over the lines on the cap, so i know that when it got hot it sprayed out the hole and now i can see that some has dripped on my engine, there is a spot on the ground now but that seems to be where the extra stuff is landing

after about an of driving today it was doing it again. i know that i have to put more in but will it stop after i do it this time, when i over filled it did i break something?
