The whistling sound is the turbochargers at work.. The turbines inside the turbos creates the whistling sound as the exhaust gasses pass by each blade of the hot turbine and the cold turbine blades drive air into the engine.
Most diesel engines are turbodiesels, and the whistling is the sound of the turbo spooling up as it creates boost.
An engine might sound like a diesel at operating temperature if the engine was a diesel or if there was an issue with the manifold. Sometimes gases escaping the manifold cover could cause the engine to sound different.
The Camry could have a vacuum leak. If there is a vacuum leak, then there can be a whistling sound until the vacuum system is full of air.
Your engine probably has a vacuum leak
check if you have an aftermarket turbo LOL
an idling diesel engine or snoring :]

Not sure what it is, mine is doing the same thing it sounds like. I am getting a whistling noise from the front right of the engine most all the time now, if i rev the engine.
