I'm getting a sound like crickets from the engine. It occurs under acceleration (even slight acceleration) and seems to be related to engine vacuum, not speed or rpm. I can't get it to happen with no engine load so I don't think it's the belt or tensioner.

It started about a month ago and is steadily getting worse.

The references I found suggest trouble with a supercharger but I don't think this engine has one, does it?

Thanks for any ideas...
