Porsche S2 high pitch whine from engine bay?
Have not located what it is, so anyone can make some guesses? I was quite sure it was the fuel pump from sitting inside car, until I realized it came from under the hood. Rollers? Waterpump? Other? I am not sure on this, but it does not seem to follow revs, or while revving, the revving noise overcomes the high pitch such that it is not hearable.
