I started pulling the engine parts from the trunk and got to looking at the supercharger and the rotors, does anyone have pictures of what their rotors look like through the opening?

Also, should the rotors spin absolutely freely when I turn the pulley?

 

the rotors will not spin absolutely free and you can googgle m62 rotor pics

 

They wont spin freely like spinning a ball bearing turbo, but they should not be binding up. If you turn the rotors and it sounds like sand spinning, or you feel a knock back and forth if you blip the pulley fast in either direction, you need to either A) disassemble and clean out the supercharger from dirt and grime or B) replace the coupler in the snout. Any sort of high mileage blower I have seen can be to some degree...pretty nasty.

 

The rotors look great, it only has 58000 miles on it, but it is pretty dirty, I'll have to do some reading and go ahead and take it apart, I wanna paint it anyways. Thanks guys

 

just check my thread in the 2.4 forum, or pm me if you need help
