I keep hearing a knocking nose on the left side of my car, I went to someone and they said it was probably a exhaust leak or something wrong with the manifold, when I rev the engine and make's a nose like air is comin outta somewhere. any help would be good though.

have someone rev the engine and check for leaks.

If it still has an air pump(attached to fornt left of the engine) that may be cracked. i don't think it would make a loud knocking noise but you never know.

Its a common problem on Caprices... 99% chance a cracked or warped exhaust manifold. Either take it to an exhaust shop or if you can work on it or know somebody do this--

Spray the manifold bolts with PB Blaster and let them sit overnight and use an impact wrench to get them out otherwise you'll probably end up with at least one broken bolt stuck in the engine head -another common problem.
