    I agree the first way to fixing a car go to a professional carmechaniker but sometimes we need to break through this rule. ActuallyI'd like to ask some guidance in connection of head gasket replaceespecially in a Toyota Estima (engine 3CTE) with same white smoke problem. I hope it's only a head gasket problem. For me is very interesting 'cos sometimes start at cold without any problem and by the way after engine heated up I have no problem with.

Dense white smoke usually indicates coolant/antifreeze getting into the combustion chambers. This can be from a "blown" head gasket or from a crack in the cylinder head or the block. In either case, this involves some major work on the engine. Replacing a head gasket is preferable cost-wise to replacing a cylinder head or the entire engine (block).

Its normal it just a moisture in your piping which causing to smoke that way...but if the smoke still when normal driving you might check the reservoir for cloudy water instead of coolant in that case you may have a blown head gasket if you got luck but if no cylinder or head are crack..anyways do not worry about white smoke you must worry if you have black smoke

Coolant problems

White smoke usually indicates water in engine. I would question the pressure test. Pull your spark plugs and check for coolant contamination on the plugs. Or rusty plugs. I'm not a mechanic but have had similar problems over the years.

My 2000 Saab 9-5 2.3T occasionally smokes a decent slightly see through cloud of white smoke on cold starts, but for the rest of the day it doesn't do it. It also has been emitting a very small cloud...

White smoke usually indicates water could be a head gasket. Blue smoke when started and between shifts could be valve seals. usually expensive to fix.

Morning White Smoke At Start-up (2003 4cyl Camry)

This problem is common but often over looked. Moisture vapor is a grayish white color but it dissipates very quickly. Smoke that is grayish white is caused specifically from burning oil. The problem you have is a small seal called a valve seal. It is very common in cars that sit a fair amount of the time. The seal gradually starts to leak and allow tiny drops of oil to drip into the combustion chamber. When the engine is started then it smokes until the oil is burned. Due to the amount of time that your car smokes after start tells me that the leak is very small. That is why there is no oil consumption. This is not going to harm the car unless it becomes very bad and then the only thing that would happen is more smoke and fouled plugs. You can start using a heavier weight oil and add an oil treatment to the oil when you have it changed. This may evin stop it all together. Hope this answered your question. Please rate this solution if you think it has helped. Good luck and thanks cj2176.

Couds of grayish smoke when starting

If it's the org. engine it will has over 200,000 miles on it.
It's normal to has the valve steam seal/oil seal on the head to leak oil into the cyclinder.

The smoke you see is the motor oil drop from the seals.

It land on the top of the cyclinders and it create black smoke at start up.

The inexpensive fix is to start using high mileage oil with seal conditioner.
This will help soften the rubber seals and help reduce internal oil leak.

The correct fix is to wait until it's time for a head gasket replacement and let the professional service the head.

Complete head service is the only method to stop this internal oil drip problem.
