Normal Operating Temp, "Woo" Sound

[JoeyTurbo]

I'm getting a "woo woo woo" type of sound (best i could describe it) from the pulley,timing belt area. At first I thought it was one of my pulleys, but I noticed it only makes the sound when the car is fully warmed up, so now i'm thinking it might be the water pump, but im not sure..Any thoughts or suggestions?

One other thing I forgot to mention. The noise rises and falls with rpm.

Anyone???

When my crank pulley seperated it started to wobble making a sort of woo woo sound that went up with the rpms. With the car off go down to the pully and push and pull on to see if it has any play. Its fairly common and a good thing to check first.

Oh and bumping is a no no

I just replaced my crank pulley not to long ago..and the sound only happens when the car is fully warmed up.

check for intake manifold leaks... i checked mine by spraying carb cleaner on my manifold and my idle increased... Resealed the manifold and the "woo" sound went away.
