Hi, I am a guy from Denmark, and I have a beautyful Cadillac Eldorado from 1972.

A week ago, suddently there came a sound from the engine compartment.

When the engine is running, it sounds like a loose bolt is being thrown around insite the engine or transmission. It it a loud "klank", "pling" noise, and it is not a regular noise, but random.

I Can't locate the sound precise, but it sounds like it comes from the bottom of the enginge or transmission.

Anyone whith a god guess to hat it could bee?

 

You could have a loose Bolt or two in the flywheel or torque converter. Maybe a rock got up in there also. Get it checked out before you drive much further.
