Hi All,
I have a 2001 Boxster automatic 127000 km on it. I bought it when it had 50,000 km. Recently its been making a loud scratching sound from the engine compartment. I took the cover off and ran the engine and started listening using a long screw driver. I initially though it was the upper roller pulley. I took the belt off and ran it for 15 seconds. The sound was gone. I assumed it was one of the components that are attached to the belt. I ended up replacing the upper roller pulley. The sound didn't go away. I took everything else apart and now I'm not sure if its the alternator that's making it or the water pump. I don't know when the water pump was replaced if at all. I know i didn't replace it. I made a video of me spinning both components by hand.
If you guys can tell me if they sound normal that would be great!
