Your engine is burning oil. The usual causes are worn out valve guides and seals, broken piston rings, worn rings and scored cylinders which all amounts to an engine overhaul. If you have a turbo charger on your vehicle, it may have gone bad.

Any oil burning will result in "blue" smoke. If you have blue smoke coming out of your exhaust, you definitely have an engine problem

If your engine is blowing blue smoke your engine is burning oil.If the smoke is present on acceleration, the piston rings are bad.If smoke is present on deceleration, then the valve guide seals are bad.

White smoke usually indicates a water leak into the engine block. Blue or black smoke would indicate an oil leak. possibly pistons!! my 88 Monte Carlo did that

What color the smoke is makes a difference, blue smoke=engine oil, black smoke=excess fuel, white smoke=engine coolant.

Blue smoke, burning oil. (tired) White smoke, burning coolant. (bad head gasket) Black smoke, excess gasoline (flooding).
