Re: blowing white smoke
Most likely yes. Look at the oil. if its milkey thats oil. If the oil looks ok have a shop look at it. A simple test can confirm this. Top the coolasnt off before you leave to go to the shop.

Blows out? Probably a head gasket. they don't always blow white smoke. Parts store sell a kit to check exhaust in the reservoir or radiator. Best bet. If it blows out, Fill it with water, leave the cap off. Start it and put your hand over the reservoir opening. You feel any pressure being cold. Head gasket.
White smoke out of the exhaust indicates moisture (water) in the exhaust. If the car is not driven very far each day, some moisture will collect in the muffler and cause white smoke for a short while after starting. If the smoke is continual, however, you need to watch you coolant level as you may have a blown head gasket.
One of the gaskets has blown at a point where the a water jacket is blowning into the cylinders but not mixing with an oil jacket on the heads. Try to use some Bars Leak and see if you can get it to seal and if not, their are also aluminum shavings mixed with sealer for some of the worse problems. If it seals you will then know that it will need a gasket replacement at some point
One of the main causes of white exhaust smoke and coolant loss is a cracked or warped cylinder head, a cracked engine block, or head gasket failure caused by overheating. A cracked head may allow coolant to leak into one or more cylinders or into the combustion chamber of the engine. Dirty coolant, a poorly maintained cooling system, a low coolant level, or a non-functioning cooling fan can cause engine overheating. In addition, engine wear can eventually cause the gaskets to lose their capacity to seal properly allowing internal coolant loss. Intake manifold gasket and head gasket failures are two of the most common sources of internal coolant loss caused by engine wear.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
white /light blue smoke is a sign of a blown head gasket or intake gasket when you changed the oil filter was it creamy cause if it was then is a head gasket
white smoke from the exhaust and overheating would almost certainly mean a blown head gasket. the head gasket has gone between a cylinder and a cooling channel so exhaust gasses can get in to the cooling system resulting in the boiling and water from the cooling system is getting into the cylinder resulting in the white smoke (actually steam) from the exhaust. the exhaust manifold is a separate issue that can be replaced when the head gasket is repaired.
Hello!
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).
Good Luck
