power steering box leaking from plates on top

if you remove that valve underneath is a jiggle pin thingy
it dicates the box bias i.e how much assist goes to left and right hand turns

when you put that valve back on there is some movement in its mounting
it needs to be moved to the correct position so that the amount of assist to the steering is the same for turning both ways

if it is really out of whack keep hands clear of steering wheel if the front end has the wheels off the ground and you start the car.

steering will very quickly go to 1 lock or the other all on its own and you don't want your knuckles rapped while you still have spannering to do..
