Ok...I'll be the first to admit that I am no expert when it comes to diesel engines. I will say this, I drove an 18 wheeler for 12 years. Every one I've ever owned, used or brand new, smoked white smoke when started....especially when cold. As soon as they warmed up a little it quit. I wouldn't rule out a worn head gasket either though. Keep an eye on your coolant level. If you aren't loosing or using any, you can probably rule out the head gasket. It could be possible that the turbo is also a little worn. But this should be a blueish white smoke. Keep an eye on your oil level. I hope that helps. Maybe someone with better info will chime in.

Yesterday you just had your oil changed in your 2007 mustang GT This morning a puff of white smoke came out the exhaust as you started it No smoke afterwards Why did it do that?

White smoke in the exhaust means water is being burned in the engine. A small puff of white smoke the first time you start a car in the morning is normal. Water condenses in the intake, and engine and when you firsts start the engine it burns off producing a puff of white smoke. It is nothing to concern yourself with unless the car is constantly blowing white smoke.


Blue smoke from engine when first started?

Blue smoke usually indicates that oil is getting into the combustion chamber. If the engine is a 2-stroke where a gas/oil mixture is used, the oil separates when not in use and the mix needs to be "shaken" before starting the engine (or the oil ratio is higher than recommended). If the engine is 4-stroke, it is likely that the valve seals are leaking.


What causes exhaust engine smoke?

If the smoke is coming from the tail pipe then: Blue smoke is primarily from internal engine wear. If it's constant when the engine is on, then the rings etc are worn and need to be replaced. If it only is blue when the engine is cold or first started, the rings are worn but not gone completely. You get the oil seeping during the night and it burns off when the car is started in the morning. Black smoke is a fuel/air mixture suggestion problems with injection or carburation. Cause of black smoke is due to running rich in the fuel air mix. White smoke can and DOES come from coolant burn off in the oil due to a leaking or blown head gasket, cracked head etc. If you aren't sure or you don't know what you're talking about, don't advise. Wrong advice can be more damaging than the actual problem.


What are some possible causes of a 300ZX putitng out a little smoke when first started?

Valve seals are dried out and need replacing if it is blue smoke. Black smoke is a sign of a overly rich condition. White smoke is a sign of coolant in the engine combustion chamber. Have this looked at by a professional ASAP. If it is indeed a coolant leak, as in a blown head gasket, serious engine damage can occur. Some steam from the tail pipe at startup is normal, and without seeing it, I could not say for sure.

White smoke is a good indication you have a blown head gasket. And/or a cracked head. Did you noticed, when it happened that the engine started running rough? Best i can do with little info.
