So I needed to change my serpentine belt today. Since I have a vortec supercharger, I needed to remove it in order to put a new belt on.
What I noticed was damage to the impeller as well as a small amount of oil.
There's a chance this could have been there for awhile. Can anyone comment if I have anything to worry about? I'm sure it may affect some hp but I want to be sure it's not a problem to use as is. The bearings are nice and tight and it spins freely.
