Blown head gaskets cause this symptom.
Also, oil leakage on to the hot parts of your engine can cause this problem.

The smoke can be either antifreeze or oil that accumulated in a plenum or low spot that gets hot when you start your engine.

    white smoke that smells sweet is antifreeze solution

    bluish smoke that smells like burnt rubber is engine oil.

3.8L rarely blow head gaskets.The upper intake plenum is leaking into the cylinders.The white smoke indicates antifreeze burning in the cylinders.Just replaced 1 on olds 98 these can eventually cause a complete no start condition.

Toyota hilux 2.4D,done overall, white smoke on start

Is it coming from your exhaust. Does it smell like antifreeze? antifreeze has a sweet smell. That could mean a bad head gasket. Since it goes away after 15km, I'm assuming the heat expansion on the engine does away with the leak. It could also mean a lot of other things. Has your engine overheated recently?

My 95 Integra LS smokes at the start 5.10 minutes late it goes away

does the oil need topping up regulary as well ?does it smoke when pulling away or when accelerating after gear change down ? smoke out exhaust indicates oil entering the cylinders, either from the valves or getting past the oil reclaim piston ring so a bit more diagnosis will be required

My 95 Integra smoke at the start white smoke what is that five minutes later it goes away

White Smoke --usually a sign of a failed head gasket
or other issue, allowing coolant into the cylinder & a major

White Smoke only on start up after sitting (Not Lasting 5 Min)
is raw fuel (gasoline) from leaking injectors, leaking fuel into
the cylinders

Injectors can fail,wear,leak or be dirty & NO you can not clean them

Forget the Genie in a Bottle The injectors have to come out & be
mailed away for Ultra-Sonic Cleaning

That condition - the raw fuel- will over heat your exhaust converter
& ruin it as well as many other problems-lack of fuel control the
main one.

My 2004 toyota sienna CE has white smoke when first started then goes away and also knocks then smokes white again when first kicking it when climbing a hill after going down another

In all the cases of white smoke it leads to a cracked head. It might be just an oil lead but most of the time its a cracked head gasket.

My 300zx got smoke issue but im not sure.smoke come both sides when i start the got little oil leak from turbos.but once engine got hot the smoke goes away.when driving it doesnt smoke.but it...

It sounds like you may need valve seals.
The oil sits in the head after the engine is cut off and leaks around the seals into the cylinder.
When you start the engine it burns the oil and sends the smoke out of the tailpipes.
It does not hurt anything much if it is not to bad.

Black Smoke and Hessitation when Accelerating

Ther are 2 sending switches at the front of the engine pop them off and look in the ends of the 1 of them has one prong the other has 2 make sure they were returned to the correct unit as they will plug on to each other. I had this same issue it also will effect how the car runs as the 2 prong one goes to the ECM to adjust the fuel mixture when the engine is cold.
