White smoke can come from your engines exhaust pipe. First you must make sure it is white and not bluish or black. Reason being, the colors indicate different problems. Black or bluish smoke indicates an internal oil leakage and burning problem. Most likely when you start to see bluish smoke from the exhaust pipe, the engine is worn out and ready to be replaced with a good used engine.

That being said, it often means that you are burning antifreeze. Check your antifreeze, have you noticed any leaking out of the reservoir tank while the engine is running? Sometimes when the head gasket goes it will produce a passage way for the antifreeze to pass into the combustion chamber. It is easy to check if you have an air compressor. Remove one of the rear spark plugs and the radiator cap. Fill the radiator and then push some air into the spark plug hole (get a good seal in case a valve is open). Repeat with all the cylinders and watch for air bubbles coming up into the radiator. If bubbles come up or fluid is pumped out, the head gasket is blown and must be replaced. It is more likely to happen at the back of the engine because it is farthest away from the fan and therefore gets less cooling.

Realistically speaking, most of us can’t and don’t want to do the above procedures, the best way to find out is to have a professional mechanic run some tests with specialized equipment designed to detect this type of problem.

After you have a good diagnosis on the problem, and assuming you have a bad head gasket or cracked head, you will need to decide if it is more cost effective to fix an old engine or swap it out for a low mileage, good used engine.
