White Smoke From Exhaust Causes

Wondering what white smoke from exhaust causes are? You've come to the right place. White smoke coming from the exhaust is normally a sign that something in your car is burning. It is a good idea to have your car looked at and serviced by a trusted mechanic if you notice white smoke coming from your exhaust. Failure to fix the problem soon enough may cause even further damage to your engine. Below are the most common causes of white smoke coming from the exhaust. 

  1. Blown head gasket. One of the most obvious signs of a blown head gasket is white smoke coming out of the exhaust. Other signs of a blown head gasket are coolant in the oil, oil in the coolant, compression loss, coolant leaks, and an overheating engine. If this is the cause of the white smoke, it can be a rather complicated and expensive repair. Although head gaskets can blow with age, this is commonly caused by overheating the engine. This is why it is very important to avoid engine overheating at all costs. 
  2. Cracked engine head. A cracked head is also a very serious repair and can be very costly. Other signs of a cracked engine head are compression loss, oil leaks, coolant leaks, engine smoke, and engine missing. If this is the cause of the white smoke coming from your tailpipe, your car may require a new engine to be fixed. 
  3. Steam. If it is cold outside when you start your engine, your car may release white steam that looks like smoke. This is completely normal and is not a cause for concern. White smoke may also indicate condensation in the combustion chambers, which should let up when the car has warmed up a bit.
