More than likely leaking fuel injector.. Causing a slight build-up of fuel on top of the piston overnight. when started it burns this off first.

SOURCE: Lexus ES300 White smoke out the exhaust no milky substance in oil

It could be the intake gaskets or even still the head gasket. How about the coolant ? Did you refill with same type coolant ? Have you noticed if it's thick and gooey ? mixing coolants will sometimes produce a thick gooey coolant that clogs up the cooling system. If the car ran hot it could also be a cracked head or block. Warped heads also. Somehow the coolant seems to be getting into the cylinder(s).

SOURCE: alot of white smoke when i turn the car on more

If the car is sluggish, it's most likely a catalytic converter based on the information you're providing. Apart from that, white smoke is also an indicator that the head gasket is bad. To check for the head gasket, Start the car and while its running, check the engine oil. If it's frothy and/or you see water beads on the dipstick, this is a good indicator of a bad head gasket. Hope this answers your question. Best of luck.

SOURCE: '92 Lexus Es 300 - White smoke from exhaust and smells like gas.

It's the ECU. Very common with the early '90s lexus cars. Everyone will say head gasket, but unless your oil is milky white, it's not coolant leaking into the cylinder.
Buy an ECu on ebay for less than $100, it plugs in under the dash, just like a computer printer. Easy fix.

99 Grand Am Smoke Exhaust


I'm sorry to say your engine may be cooked.
Since you are adding both oil and coolant, and the color of the smoke is gray or white, you have the signs of the engine burning coolant.
The common cause is a leaking head gasket.

Whenever I start the car it smokes than after warming up it stops smoking.


The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?

Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.

Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.

If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.

What are you consuming, fluid wise, will direct where you go next.

What is causing white smoke coming out of the mufflers when I start the engine?


It's normal for a thin white smoke to come out of the exhaust at initial start up. This is caused from moisture built up in the exhaust burning off. However if there is a continuous flow of thick white smoke it could be a blown head gasket causing coolant to burn.

When I start my 2003 ES300 smoke comes out the exhaust


The same thing happened to my 2003 ES300 - the smoke is coming from the oil seeping into the motor's cylinders. This is the classic "Oil Gelling" problem in Toyota and Lexus vehicles. There is a factory recall on it, but it only covers to 2002 ES300 not 2003. The Lexus dealer confirmed my "oil gel" problem and went to bat for me with Lexus - they got the repair approved - Thank you Mr Local Lexus Dealer! The cost was nearly $4,000 - paid for by Lexus.

Blown Lexus ls400 engine


Smoke is a sign of engine burning oil, which is caused by faulty piston rings, in most cases it's cheaper to have another engine installed in the car, instead of having work done on pistons. Hope this helps and please rate the answer if it was helpful, it helps me, thanks! P.S. Comment if you need more advice, it'll be my pleasure to assist you.

White smoke exhaust


White smoke is caused by coolant or water coming out the tail pipe. There is a chance that the white smoke was caused by water splashing up from a puddle onto the exhaust pipe. Keep an eye on the coolant level in the radiator in any event. If its less then there leak coolant leak in the car engine which is causing this problem....
