Hey guys, I have had this noise coming from my car for a while now, but I finally had time to post up a video of it. Its kind of a metallicy screeching noise that is coming from under the car. You can hear it inside the car and barely in the engine bay (which makes me believe it is not a belt type issue). It only happens when the engine is cold (lol especially now its inthe 20's outside), once the engine warms up it goes away. It does get higher in pitch with rpm's and you can tell that a little bit from the second video when I rev it up barely. Do you think it could be uneven cylinder wear? Here are 2 videos... Its really disturbing me and any help is greatly appreciated. Thanks in advance

So does it make a noice when that car is cold. What about when the car is warm and when you rev it?

If it dose it when it's warm or cold I'm thinking it could be a throw out bearing or a pilot bearing. It's if the car is a man.

Yeah its a boy. The sound goes away once the engine is warm and the sound increases (goes faster/higher pitch) when the rpm's of the engine go up.

I'm still stuck.
So the fast high pitch goes way when the motor is warm?
What do you mean"when the rpm's of the engine go up"?
They go up when starting the cold motor. Or when the rpms go up when driving and it makes the noice be it ether cold or warm?

I'm sorry for the confushion!

[bmorestang]

haha its ok. The noise goes away completely when the engine warms up. If I rev the engine up the noise will also change and start to go faster/higher pitch, etc...

I'm at a loss for words. You hear little of it coming from the from end. But more of it in the car. I'm thinking it could be a t-bearing or pilot bearing just really cold. Or something with the tranns.
Did it ever do it when I was warm out side? You'll fine many noises in a car when it's really cold out.
Just to days ago by me it was -10 to -20 with the wind chill. And I heard tons of different noises that I did hear before in the winter and they to go away when it's warm.

You should check the bearing on the output shaft right before the yoke it will most likely be this bearing , if you dont hear it anywhere but in and under the car.

It sounds clutch related to me. Drive it until it breaks, then we will all know when ours do the same thing.
