I would suspect the valve seals are bad. This allows oil to run down the valve stem and enter the combustion chamber when the engine sits overnight. Unless the smoking and oil consumption is excessive, I would not have this repaired as of yet. Although the head does not have to be removed to facilitate repair, it will require valve cover removal, and can be expensive due to the labor cost.

Because the engine is a boxer type six with horizontal pistons, the oil will often drip into the cylinders. this often leads to white smoke on startup. If the smoke is minimal and only on start up after sitting for more than a day, not much to worry about.

I don't think it makes a difference one way or the other.

bcoz the smoke has " demiculogrologist " which is a special type of chemical which makes all this happen.......... 'cauze this chemical is a ........................

White smoke at startup, loss of anti freeze and milky oil indicates to me a bad head gasket.

No car engine should smoke from the hood on startup. The color of the smoke will indicate the problem. White thick smoke indicates burning oil, while grey smoke indicates an exhaust issue.?รฆ

Depends on when you see smoke, and what engine. The most common is smoke on startup indicating worn out valve seals. Other times are probably a deeper issue.

White smoke at startup (when the engine and exhaust have completely cooled down) is usually caused by condensation. It's especially noticeable in cooler weather when the car is used for short trips. The engine never really gets totally warmed up, existing condensation in the exhaust isn't completely evaporated. In short, what you may be seeing is simply steam vapor. If the smoke isn't white but is more gray or blue/white it's oil. A few seconds of oil smoke at startup is usually caused by leaking valve stem seals. Oil drips down the valves and onto piston tops when the engine is idle. On startup the oil is burned causing a few seconds of smoke. The puff of burning oil is most noticeable after the car has been sitting awhile, like overnight. Unless the seals are really bad not enough oil drips into the combustion chamber during shorter stops to notice any smoke. Cheers

White smoke = Blown Head Gasket or cracked head. Black Smoke = Overly rich fuel/air mixture. Blue smoke = Oil burning. Blue smoke at startup usually means worn valve seals.

White smoke when cold - normal condensation burning off Blue smoke when engine is at normal operating temperature - could be bad valve guides or seals.

When you are sitting in a room and you're (willingly or unwillingly) inhaling the smoke from a pipe/cigarette/joint without actually smoking it yourself.

When you smoke your teeth do go yellow and fall out gradually.

If it only smokes at startup and the smoke is blue this is normally a sign of worn valve seals or guides. White smoke is a symptom of blown head gasket. Black smoke is a symptom of overly rich fuel/air mixture.

Nothing that wouldn't normally happen when you smoke.

what makes air dirty ?

people smoke cannabis because it makes them feel better about themselves

What color the smoke is makes a difference, blue smoke=engine oil, black smoke=excess fuel, white smoke=engine coolant.

User Avatar

White smoke from the exhaust is a symptom of moisture in the combustion chamber. If you see it after that initial startup, then suspect a blown head gasket. A compression test will verify this.

Black smoke, from any diesel, is the result of partially burned fuel. Overfueling will cause black smoke.
