Hey guys, just need some input on what to do, I have a 91 S13 with KA24DE. I recently replaced my PS system with a Chase Bays Kit. I had a bad pump, so I went ahead and bought a brand new one. I have zero leaks, and am using ATF for fluid. My problem is even after replacing everything the pump is still whining like crazy, far worse than the old pump. The belt is in good shape, im wondering if the issue behind the heavy whine is due to air pockets?? If so whats the best method of fixing that? And do you guys have any other thoughts on why it might be doing this?
