i dunno why this happened - it's my power steering resevoir. on my 6.2, it's remotely located above the pump. about a week and a half ago i noticed that there was a gaping hole in my resevoir, so i topped it off over and over till i could get it fixed - they don't make replacements. i was thinking about using a water bottle, but figured i'd try and weld it liquid-tight.
turned out perfect and doesn't leak.... so taht's cool!
