Engine makes a whistle sound. Just sometimes. It is real loud at times like a coach's whistle blow then other times it is just whistle whir or click under the hood.
I have a '97 Ford Taurus, and my car is also making a whistling noise. I live in South Bend, IN, and lately it has been pretty cold and snowy. I'm wondering if this could have anything to do with it. I also noticed just tonight that it starts whistling right at 25 mph.
PS. Does the '97 actually have a bypass valve? And is the noise I'm hearing mean that it's working? I have a '97 Ford Taurus, and my car is also making a whistling noise.

My wife has a 2005 Ford Taurus and it seems to have the same problem. It started whistling a couple months ago when the winter weather came (I live in Indy) so I guess it could have somthing to do with it (cold air making the sound??). I hope it is what you say it is (air bypass valve) and nothing more serious. The valve doesn't cost much (just about $50) and seems like an easy fix...My wife has a 2005 Ford Taurus and it seems to have the same problem.

Sounds like a vacuum leak has developed in the intake system. While the engine is whistling, using a spray bottle with water and on the mist setting, spray along the intake manifold area and vacuum hoses to locate a possible leak.
CYLINDER 3 MISFIRE COULD BE LOOSE SPARK PLUG OR CROSS THREAD SPARK PLUG TO CYLINDER 3 THE CYLINDER COMPRESSION IS BLOWING BY SPARK PLUG MAKING A WHISTLE NOISE.
Have the prop shaft looked at. The prop shaft center bearing's go bad and make a whistling sound. Sometimes this is it it seems to be a common problem on theses vehicles sorry it can be fixed by a mechanic
I would have the converter checked for back pressure. if it is plugged it can cause excessive Engine pressure. if it is not plugged then you have excessive blow by or a malfunctioning PCV system it sounds like.
Sounds like a vacuum leak. Check all vacuum hoses on the intake, throttle body, etc. Sounds like one cracked or came off. Post back if you have any questions. Hope this helps.
