power steering pump

I think my PS pump is going out. I found two golf ball sized oil spots on the garage floor with really black looking oil. I just changed the engine oil last week so that is still really clean and isnt black. I just got an 8 rib belt conversion and right after the install, Ive had this really high pitched whine with a moaning sound. I wonder if the conversion with the new pulley somehow killed the stock PS pump. It has 30K miles on it. Do they make any performance PS pumps that are better than stock?

I was just under my car for looking for any wet spots or drips. Its dry as a bone. I have no idea what the hell those spots are from on the floor. But i still have the groan. I'm not sure if the groan is something that comes with going with an 8 rib setup, dont see why it would.

I tried to pinpoint the location of the groan, which is kinda hard, but seems to be coming from the alternator area, maybe lower, but around that area. I'm confused The fluid level is fine, when its cold, its barely below the max line and once i start it, the level seems to come up to the max line.
