I want to state right up front that I am just a girl, and know about cars only what I have learned from my mechanic dad and mechanic husband, so please bear with me if I use the wrong terms, etc. My daughter has a 1997 Chev Cavalier that keeps blowing O rings in the power steering system. She has had the rack and pinion recall done, but was having this problem before then, and still is. It seems like the system must be building up too much pressure? Sometimes the O ring will last for weeks, sometimes the 250 mile trip from her house to ours will cause it to go. Then the PS fluid leaks out and she has to fill the reservoir every day or so. Has anyone had this problem, and if so, what did you do to solve it. We thought it was a faulty PS pump, but have changed that 3 times, to no avail. Any thoughts would be greatly appreciated!! Thanks from a newbie.
