SOURCE: Burning oil

Hi again,

For some unknown reason(s) the Live Session/Chat was disconnected. Our apologies for any inconvenience.

In any case to finish the 2nd suggestion. You may want to discuss this issue (smoke and oil consumption) with your dealer. Cite a Lexus Technical Service Bulletin specifically addressing this issue "Excessive oil consumption caused by sludge buildup on the cylinder heads. Company is extending warranty. (1997-2001)".

You may want to reference this USA Today article or the discussion in this page.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

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 ofwhite smoke coming from tail pipe

Not sounding good if white smoke, usually indicates coolant into cylinders via bad head gasket or head, maybe intake leak, or piston rings gone. You, or someone didn't overfill oil by chance did you?
What's mileage & did you have any warning signs or did this just happen all of a sudden.

SOURCE: 1994 Lexus ES300 large cloud of smoke.

Valve stem seals can cause this problem, but normally only when first started. Oil in the rocker cover seaps through the oil seals into the cylinders and is burnt up on start up.
Try a "STOP A LEAK" additive and it may reduce the oil consumption and smoke.
I found some on e-bay and it worked on my tired old escort. It even stopped the rattling tappets.

SOURCE: i have lots of white smoke coming from tail pipe

White smoke is either steam or coolant. Oil smoke is blue, fuel is black. The smoke is water or coolant boiling and then coming out the exhaust as vapor.

If the weather is cold, water will condense in the exhaust system after shutdown, then come out as steam on startup. This is OK. If you see the smoke after driving on the highway for an hour or it is an all-the-time event, you have a problem.

If you have a problem, most likely, at this age, it is a leaking head gasket. Possibly the cylinder head is cracked. Valve problems are possible but less likely. Keep track of how much coolant you add to keep it at the full mark. Obviously, this is expensive to fix.

The problem was bad/worn valve stem seals which allowed oil to seep into the cylinder heads when the engine wasn't running and burn off when the engine was started creating the white smoke. If it is valve stem seals, they are not too expensive to replace however I would suspect your mechanic will want to do a complete valve job which is a little more costly.

Hope thos help (remember comment and rated this).

After Idle for a while as I drive away there's a lot of smoke that comes out of the exhaust pipe kind of white and bluish


Thats oil caused by "blow by" it means your piston rings are wearing out or you have scratches in the cylinder walls, causing oil to "blow by" the rings and burn during spark. Only way to permanantly fix is to rebuild. You may get temp fix by using a product called restore. It is sold at autoparts stores.

Car wouldn't start, but when it did it was smoking


One thing used many mechanics for diagnosis is: What color was the smoke?
White smoke usually means the engine is failing, and can indicate a leaking head gasklet, a cracked block, or a cracked head. This color smoke is from water and/or coolant getting into the cylinders.
Black smoke indicated too much fuel, and the engine may be "flooded", indicating a less expensidve fix.
Grey smoke indicates oil smoke from worn rings or worn valve stem seals.
The white smoke says you should have someone look at this really quickly to see if immediate attention is needed.

White smoke coming out of tail pipe.


WHITE smoke? Or BLUE smoke? White smoke is usually caused by burning antifreeze (possible blown head gasket). Engine oil burning causes a bluish colored smoke.

Changing the oil two months ago means absolutely nothing to me. I have customers that travel 6000 miles or more in a month. Oil consumption is measured in volume over miles, not volume over months. It is normal for most 4 cylinder engines to use a little less than 1/2 quart in 1000 miles (even more than that for 6 cylinder and 8 cylinder engines).

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.

Smoking white smoke at idal and lots of black at 1500 and above . a little miss at 1500rpms no power lose


Black smoke is a sign of an overly rich fuel/air mixture. White smoke is a sign of coolant entering the combustion chamber. Most likely you have a blown head gasket. Other symptoms are loss of coolant with no apparent leak, loss of power, miss, oil level overfull, a white foamy substance on the underside of the oil fill cap. Stop driving this truck until you find the problem. Driving it with a blown head gasket will destroy the engine. A compression test will verify this.

I have a diesel engine that expells white smoke for 5 to 10 miniuts after start up? The exhaust also smells rich with fuel? I bought the truck used and am trying to fix the problems! Please help.


When an engine expels black smoke it means that the piston rings are going and is consuming oil. And when the color of smoke is white the engine is consuming more fuel. Both are harmful. Black to the engine and pocket while white to the pocket. It seems that the injector need careful attention.
Cold engine does expel white smoke initially. When the temperature rises to normal working temperature the smoke stops. This is normal in your case. 5 to 10 minutes to warm up is normal for any diesel engine. But any thing more than that needs attention.

White smoke from exhaust


Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;
