Over the past couple days, Ive been hearing the noise, and its gotten worse. Now Im starting to think it may be a collapsed lifter cuz I can hear it revving in park. I mostly hear it when my car hits overdrive, and I cant put more than a 1/4 throttle on the gas or else I hear it :-/ . I thought it coulda been the power steering pulley cuz it was bent and falling off.... wrong. I replaced the whole pump today and its still making the nasty racket. As long as I got something good outta replacing the pump, cuz it definately feels like my steering is 3x better
