I pulled my car in the garage this evening and heard a sound I never heard before. It is like a combination of a metal on metal light grinding and rattle noise. It is coming from the from the front of the engine. I can only hear it at idle. As I gave it gas in neutral, I could not hear it over the sound of the engine. While driving I did not notice any loss of power. This sound is new and I know something is not right. Can anyone tell me what to look for?

Also, while revving up the car in neutral, the most I could get the RPMs up to was 4000. Is this a safety feature?

Thanks,

Most likely a sc bearing.
Any mods?

Pull the belt and check - it will not spin smooth.

Ebay-unless there are still some here

And yes the rpm limit is a safety feature.

 

Thanks for replying. I worked on the car some today and it was a bearing, but not the SC Bearing. While the engine was idling, I took a screw driver and held it against the inside wall of the pulley below the SC Pulley and to the left the water hose. When I did this the sound stopped. I removed the belt and pulley and the bearing was so loose inside that I could move it up and down with my finger. I would think it should go for the price of the SC Bearing.

Thanks again,

Glad you caught it before it let loose - can cause some nice damage.
