Usually when you have a rattling sound or knocking sound that is the sound of a connecting rod about to fail and the smoke is from the piston and piston ring failure which allows oil to pass through where the piston rings seat on the wall and enter the combustion camber. Is the engine consuming oil?

Blue smoke is usually oil burning, like bigboy stated it is an internal engine problem developing, the only way to find out what it it is will be an engine tear down.
