What would cause a knocking noise when the engine is cold on a Chevy Tahoe?

There are 2 typical noises that can be called knocking with the engine cold, that descreases or goes away when warm. The first is a minor problem, but still should be corrected before it creates a big problem - one or more hydraulic lifters "stuck"; as the oil heats up this can often clear itself up. The second is a more major problem, and that is connecting rod knock, usually indicating the bushings are bad and will eventually lead to destruction of the engine if not fixed. There are other noises that change with temperature, but these are the most likely ones you have experienced.
