When smoking on a Smokey Mountain expect to see some white smoke while you are getting the smoker up to temperature. It should take no longer than 30-45 minutes for the white smoke to stop though.

What causes excessive white smoke?

Many times, this thick smoke is due to the likes of a blown head gasket, damaged cylinder, or a cracked engine block, which is causing coolant to burn. Thick white exhaust smoke usually indicates a coolant leak, which could cause overheating and put your engine at a serious risk of damage.

Can changing oil stop white smoke?

Not unless you're pouring it down the carburetor. Seriously, white smoke would indicate oil in the combustion chamber, but a normal oil change should not cause this.

What to do if white smoke is coming from exhaust?

K-Seal can fix water loss and white smoke from your car exhaust. 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.

Can misfires cause white smoke?

The misfire alone is not enough to deem a blown head gasket. The fact that you have the white smoke present along with the misfire is sound evidence that this is the case. The white smoke means you are burning engine coolant inside the engine. The vehicle is likely cutting off due to high engine temperatures.

Can bad fuel cause white smoke?
