Ok I have gone through 3 power steering pumps two in last two days! Yesterday it made bad sound just like first one a month ago! Today I got another one I installed it first and it leaked like a sib I had my nabour come over he put a bigger o ring on the resavore and it leaked two he had to leave so I pulled it off again and put a smaller I ring on after re intaling and bleeding air bubbles it didnt leak I drove to my house and it started to drip a tad bit more! What is wrong? What soze o ring is recomend? Should it be hard or easy to get resavore on? Any tips are appreciated at this point I could specialize in power steering I've changed it so many times!
