Very loud clanging noises started while driving

I developed very loud clanging noises while driving my 1984 corvette. while stopped at a stop light smoke came from under the hood. I continued to drive it for about 1/2 mile to get it home. temp was 200 oil pressure 60 at time of driving. No smoke came out from the tail pipes. I raised the hood and light smoke was around the drive belt/air conditioning unit side. I could see what looked like oil or something on the inside of the hood that would have been right above the air conditioning unit and drive belt on the pulley ?? in front of the air conditioning unit. I tried to start the car again the next day and a very loud noise was associated with it turning over, so I shut it off. The car has 20,000 miles on it, I only drive it in nice weather and store it for the winter. Not sure who to call or say what is wrong with it. Any help would be appreciated.

Try to remove the belt for the ac and see if you still hear the noise, as it sounds like you may have blown the seal or bearing out of the ac compressor , not sure just a guess.

Might be a louse belt, air in the steering rocker arm system, a bad CW joint, or anything else. Try to locate the source of the noise first.

Your diagnosis could be correct though few vehicles these days have an adjustable clutch.

A loud clang isn't a noise commonly associated with clutch problems.

02 4x4 olds bravada makes loud clanging noise when turning wheel

Have your CV boots and half shafts checked. If these are cracked, they will dry out and cause a lot of noise when turning. Also check your swaybar links, these cause a lot of noise also, but not only while turning.
