I had that too above 3000 RPM a while ago, and that fixed it. Dieter |

Try things already mentioned . . . another thought, 5- or 7-bladed WP fan? 7-bladed fans are particularly noisy, high pitched whine, at higher RPMs!
. . . nature of the beast, I'm afraid.

Try isolating the noise using a 2 or 3 ft length of hose as a stethoscope
holding one end to an ear and searching for the source. Have someone rev the engine while you're doing it. This might be kind of scary.
