Hello my 1989 (first gen) 4runners power steering is using fluid, but I can find no leaks. I can't figure out where its going ,but I have to add fluid about every other day.Its only a few oz but what the heck . Is the power steering fluid going into one of the vac lines that come into a valve at the bottom rear of the pump? <img src="/forums/images/graemlins/confused.gif" alt="" />
