Trick for finding elusive noise in car
Anyone ever hear of this trick? A guy told me that if you were searching for a noise, to take a large screwdriver and place the handle near your ear and point the shaft to where you think the noise is coming from. The screw driver will act as a "stethescope". Not sure if he just wants to see me walking around my car with a sscew driver in my ear, but it sort of sounds logical.

I like the image of a banana, but the way I heard it is:
to find the source of a noise inside the engine,you place the screwdriver blade on various parts of the engine, and the end of the handle against your ear.
Don't know if it works in the air, but if you try it, please post pictures

but you may be right about physical contact.

For 9.99 you can buy automotive stethoscope from any auto parts supply store. Carefull the first time you put the headpiece on the sound is magnified to the point that banging the tip can cause ear damage.
You will also get to eat the banana without getting ear wax on it first.

Yes, this is actually a valid technique. It's no good for a suspension clunk (unless you're very very small and can cling to the underside of the car while it's moving). But for isolating a noise w/in the engine or tranny while it's idling, you bet.
The longer the screwdriver shaft, the further you can keep your face from the moving belts, fan blades, etc.

I have one of these (different brand than the picture). It has proven helpful, but not magical. A screwdriver works, but this is better. You don’t have to turn your head sideways to put you ear on the top of the screwdriver, so you can look at what the stethoscope is touching. The probe is narrower and longer than a screwdriver, so it fits in smaller, harder to reach places, and you can stay further away from moving stuff, like Robert mentions.
Like LAT says, it really does amplify the sound a lot, so be careful not to hurt your ears. They’re cheap, too.
