Mystery Noise!
So starting about two weeks ago my car started making a strange sound...its the engine and its not knocking , but it has this weird whining sound to it. It is still performing top shape and everything seems good to go except that weird noise. My oil is full its idle is normal I just don't get it, but the sound is getting louder...Any ideas?

Might check...

Is it constant or periodic?? probably not the Power steering pump but could make a weird whining periodic sound. Good luck, Keith |

I recently had a smililar problem with a "whinny sound" coming from my engine, but the car ran perfectly and I couldn't find the origin of the sound. Then a month or so later I found out the hard way.
The sound became a screech...within seconds the smell of burning rubber, then my dash lights all came on. I pulled over opened the hood to see a belt melted and broken. The noise I'd been hearing was caused by the bearings on the idler arm pulley slowly failing until it seized. Not a big deal depending on where you are when it happens.

Two other things to diagnose;
- Is the Power Steering fluid "frothy" if so you need to replace the PS tank O-ring, there is a right up in the How-To documents at the top of the page. - Next is to take both of the front belts off. Start the engine, if the sound is not there we are close to identifying the problem. With the belts still off, spin all of the pulley's and idlers, are any of them hard to turn or make a slight noise? That's probably the one.

Thanks guys I guess I'll go poke around.
...And Keith, yes the sound is constant and when I step on the gas the sound changes pitch depending on how fast or slow I drive...which makes me also think its the belts or a pulley...don't know much about bearings, but I'll figure it out. |

Does it make the noise when the engine is spinning but the car isn't moving?

Just kidding!
I am a big tease...
That is all I would know to call it but I couldn't spell it! Had to do a copy paste on yours... Take care, Keith |
