Can a faulty spark plug make your car blow white smoke out?
No, If the plug isn’t firing the vehicle engine would be running rough because it is missing and the unburned fuel will cause black smoke not white or grey. First look to see if it’s actually smoke or steam. Steam will dissipate almost immediately where smoke will linger much longer.
Where does the smoke come from in a spark plug?

What makes white smoke come out of exhaust?
This can be checked with a compression test, also you will have oil start to show up in your coolant. On the other hand, if you get a white smoke and after your car warms up it goes away. It’s usually just water that has condensed in your exhaust system.
What causes a bad spark plug in a car?
Low coolant or exhaust gas in the coolant points to a bad head gasket or cracked head. Oil consumption can be valve guides or piston rings. Gas soaked spark plug indicates ignition failure – which is usually not the spark plug itself unless they’re really neglected.

Can a bad head gasket cause white smoke?
Yes – completely unburned fuel makes white/grey smoke, but so does coolant and oil. It’s going to take some diagnosis to determine the source. Low coolant or exhaust gas in the coolant points to a bad head gasket or cracked head.
Why does my car blow smoke when I start the engine?
In other words, oil is getting into the combustion chamber somehow. Usually the smoke is from worn or damaged piston rings especially when accelerating. Oil is getting by the compression ring either because it is worn or maybe cracked. If the smoke is noticed when the engine is cold started the problem may be with the valves.
