6.0 making odd noise after shut off.

It sounds like a pump running. When i drive the truck and shut it off, it continues to run. if i cycle the key to on and then back off it stops. Truck is a 03, with an auto and about 200K on it. Any ideas? I can video tape the noise if need be.

ford said my oil in my 6.4 being 2 quarts over full was fine too, and that if my wife didnt like it, she could "just drain some out" mind you, she's 8 months pregnant. They also cant find the leak in my radiator that i even brought them pictures of. When they say something is normal, it just scares me.

A friend of mine has an 06 and it did the same thing. He took it in for a bad injector and when they replaced it started doing that "buzzing" sound. He took it back and they reflashed the computer again and that fixed the noise.
