Scree…
My freshly restored 1958 Giulietta Spider Veloce developed a wheezing, kazoo like sound coming from the engine. My first guess was a cylinder's header pipe was loose at the head, causing the thin cooper gasket to sound like a reed in a wind instrument. Nada. An expert's ear guessed it could be a dry cam bearing, yikes but nope, the caps were oily. The source I found finally was all eight impossible to access nuts that secure the DCO3 Webers. They were just finger tight. It takes a special set of crippled 12mm wrenches to fix that.
