White smoke from your exhaust means coolant is exposed to your engine`s combustion process. In most cases, this is the result of a blown head gasket, but a cracked engine block or cylinder head could also be the cause.
White smoke usually means coolant is getting into the combustion chambers of your vehicle. This generally happens because of a cracked or leaking head gasket, which allows coolant to seep into your cylinders. In extreme cases, you will need to replace your head gasket.
White Exhaust Smoke

White smoke billowing out of your exhaust means that coolant is likely leaking into the cylinders. This usually happens when there has been a breach in the head gasket, which makes the coolant create this white steam.

White Smoke

It usually means that coolant is being burned in the engine, which means that something is drastically wrong. The most common cause of this is a blown head gasket, which can quickly lead to an overheating engine.

The two most common causes of white smoke coming from the engine are oil leaking and an error in the Engine Control Module. Oil leaking. If white smoke comes from under the hood, particularly from the engine, smells like tar or asphalt, and has a bluish tone – the oil is probably burning inside your vehicle.
What Should I Do If I See White Smoke Coming From The Exhaust? It`s recommended that you stop driving your car. Driving when you see an outpouring of exhaust smoke can cause your car to overheat due to a coolant leak. This could severely damage many engine parts.
White smoke is a result of unburned fuel particles passing through your car`s combustion chamber and out of the exhaust pipe. As previously mentioned, white smoke is related to lower temperatures in the combustion chamber. When the chamber isn`t hot enough, some fuel particles fail to ignite.
A perforation to your gasket or a blown head gasket usually occurs as a result of an overheated engine. When coolant flows into the combustion chamber from a blown head gasket it burns/evaporates into white smoke.
This means that the fuel injectors are either adding too much fuel or that the intake valves aren`t letting enough air in. This could be caused by a leaking fuel injector, a faulty fuel pressure regulator, or a bad air filter. If your engine is running this rich, it can cause serious problems.
Thick white smoke pouring from the exhaust is usually due to a crack in the cylinder head, engine block or head gasket. This is caused by constant temperature fluctuations and a consistently overheating engine due to low coolant levels.

Normally white smoke coming out of the exaust will me one of two things.
You have overfilled the crankcase with too much oil and it is making the smoke, in which case you can drain the excess oil out and that should elimanate the white smoke.
Or, you have a worn out engine and oil is getting by the rings of the piston and being burnt in the combustion chamber of the engine.Which means engine overhaul, or buy a new mower.
