Answers:
IS THE SMOKE WHITE? CHECK THE OIL IS IT A CREAMY COLOR? IF SO HEAD GASKET. COULD ALSO BE A ROD.
DO YOU CHANGE OIL REEGULARLY? A MASSIVE AMOUNT OF WHITE SMOKE CAN MEAN BURNING OIL OR WATER IN THE CRANK CASE. DID THE CAR OVER HEAT. IF NOT ITS PROBABLY A ROD AND SERIOUS DAMAGE. DO NOT START THE CAR AGAIN UNTIL YOU HAVE IT REPAIRED YOU POSSIBLY CAUSE MORE DAMAGE. THE MORE I THANK ABOUT IT I THANK ITS A ROD.
If it is white smoke your engine has a serious problem, pure black smoke means too much fuel, I would guess from what you said that it is a bearing in the engine on the crankshaft or piston rod, it is causing one piston hang up or wobble which makes noise, smoke, and a lot of power loss.
