Bell Housing Noise

I don't know for sure with 810-12 Cords but with L-29 Cords never run the car with it on a hoist. You will destroy the cones that center the inner U joints.

My first guess would be your throw out bearing is going out.You have a clutch manufactured by Long in your Cord. One of the features of a Long clutch is that when you increase the engine speed the arms on your clutch increase the pressure on the clutch disc. This will force the arms of the clutch to move out. When this happens it decreases the clearance between the clutch arms and the throw out bearing. This is a good feature as it puts more pressure on the disc and prevents it from slipping. You state that the noise is there only when you increase the engine speed which tells me it is probably what is happening. I suggest you check this out by increasing the clearance on your clutch so that you have to push the pedal down farther before the clutch is disengaged. If you don't hear the noise when you jack the car up then the throw out bearing is your problem. You might not have had enough clearance on your clutch causing the throw out bearing to be engaged when you were driving. You might drive it if the noise isn't there when you jack it up. Your choice and good luck.

Don't sweat the swing arms- I have rebuilt my entire car on a two post hoist for the last 20+ years- it just touched the ground this year- I lift just under the joint for the firewall connection and the rear spring shackles-a couple of jack post as well for personal comfort when I am really turfing on the front of the car.

I had a similar rattle some time ago- hard to diagnose from far away but I had loose (destroyed) bearings for the clutch actuator shaft where it enters and exits the bell housing- substituted oil lite bushings.

Hi everyone,

While driving my 810 Westchester home from a Concours Show last Sunday, I noticed a new noise coming from the engine compartment as I drove in my garage. It is kind of a rattling noise when you rev the engine, you hardly hear it when you are driving. I took it to my mechanic today and we jacked it up, put jack stands under it and we climbed under it with the engine running. The noise is seems to be coming from the bell housing. You only hear it when you rev the engine just a little. The car shifts fine, but you definite hear the noise when you drive off. Any ideas? I was wondering about the pressure plate or clutch but remember it shifts fine. My mechanic wants to put it up on a lift but is a little concerned using a modern lift with swing arms. He is not sure where to place the arms under the Cord. Looks like I will not be bring the Cord to Auburn this year.
