While you have clean, clear access to the PS pump, clean it up nice, stake the hole in the back, then fill with epoxy (JB Weld). This is to prevent the plug in the back from blowing out and rendering it undriveable due to loss of PS oil.
Learn new stuff on here every day. I'll search this topic up and see how to do it, as I am in the process of pulling my engine as well. Thanks for the pointer.
