broken oil scraper ring, low oil level.
It's not smoke, it's steam. When the water in the air passes through the airplane's engines, it warms up and becomes steam.
Smoke is usually the result of a combustion process that releases heat. This heat warms the air containing the smoke and as warm air is lighter (less dense) than cold air, the air and smoke rises.
It has a leaking head gasket or a crack in the cylinder head.
If you 4.3 liter begins to smoke as it warms up, it might have an oil leak that is causing the smoke. Often, the oil will leak once the engine reaches operating temperature and it thins. or it might be the valve seats going bad because my truck does the same thing and its the valve seats
Usually white smoke is the result of a cold engine. After the engine warms up, the white smoke should disappear. Faulty injector spray patterns are another common problem.
White smoke is usually a symptom of a bad head gasket leaking coolant into the cylinder. If the white smoke stops after it warms up it could just be condensation from sitting for a while.
White smoke out of the exhaust is a sign that the head gasket is bad and is allowing water (coolant) into one or more of the cylinders. If the smoke decreases when the engine warms up, this may mean that the gasket is expanding when the engine warms up. Check for coolant in the oil by looking at the oil on the dipstick. A sure way to tell is to tell is that the oil will be a milky color and overfull.
Sounds to me like a cracked cylinder head.
is this a diesel truck?does this engine have a turbo?if it is a diesel with a turbo,it will blow white smoke when cold till it warms upif it continues to blow smoke check your air filterother reason if it continues to blow smoke is the turbo is about to crater get it checkedalso check engine oil for coolant lossif coolant is leaking into cylanders,this will cause white smoke
Yes, it's just condensation....as long ads there is no trace of smoke at all once it warms up. If there is some smoke with a sweet smell to it,then the head gasket or head itself is cracked.
Sorry to tell you but you have a blown head gasket, cracked head, or both. The white smoke is coolant entering the combustion chamber. STOP driving this vehicle or you will destroy the engine. You must have this repaired and it is not cheap.
The land warms faster
