My answer to everything: Silicone!
Disconnect the actual air hose from the top of the pump so you dont spray silicone into your cats. Then get some wd-40 or tire wet and douse the pump. If you can, remove the front pulley and the output neck on the top and spray into the fins on the front and into the air neck on the side. Also, get a straw and spray into the little breather hole on the back. Then try and cover it with as much paper towels as you can, reattach the pulley and start the car! What a mess, but it beats replacing the pump! She'll not make a peep for at least a month.
I have a special smog pump that I use to pass emissions with. I call it the smog-charger! It's a seized up smog pump from years ago. I disassembled it, sanded the inside for some extra clearance, drilled out the leftover stock alternator pulley from my OD pulley install and attached it to the front of the smog pump. I then filled the inside with 5000 grit sanding jel and ran the motor for a few minutes. To smooth everything down. Then I siliconed it, reassembled and viola! Poor man's supercharger! This thing FLOWS. It's ridiculous how much air comes out of an airpump spinning 3x as fast as it was meant to. Sounds like a cessna! BZZZZZZZ! It will sieze up again after about 20-25 minutes from the heat (I guess I need to sand more) but it's just enough to pass emissions with flying colors!
