Sounds like a head gasket leak if the car is leaking gas DO NOT drive it if the gas is hitting the exhaust it will catch fire

White smoke from BMW 740i exhaust


white were? the exhaust tip, or other spot, long pipe, name spot?
white, is steam or OIL.
oil smells like burnt oil and takes for ever to dispate
steam is water, and smells , sweet due to 50% glycol inside.
and goes away fast.
but all Gas engines make water at all the time running as a by product of combustion and for sure on cold days, some times full time cold
due to climate effects.
does your neighbors car smoke at same time, (look)
bingo , dew point.

all gas engine smoke cold started, (steam)

so first find out what it is,
take the dip stick out of a hot engine. stalled, drip it on the exhaust
see that smoke ,smell it? that is burning oil
now you know what you have, steam or oil. smoke.

Blowing white smoke out of exhaust pipe


White smoke is usually a sign for a bad head gasket. How much white smoke is coming out? Also, are you losing coolant and can't find a drip under the engine?

Valve guide seals


Are you saying you have smoke coming out of the tail pipe ? Or is something dripping onto the exhaust pipe and burning ?
If the smoke is coming out of the tail pipe, is it blue, white, or black ?

Alot ofwhite smoke coming from tail pipe


Have you overheated or are loosing coolant? If not check to see if your transmission has a vacuum hose going to it. (if coolant you can smell it in the exhaust)
I don't think you have the trans hook up but can't remember.

My lexus is smoking from the exhaust pipe every time i press the gas


if it is white smoke the rings are going out. if its black smoke its running to rich. if it smokes on first start up and then clears out it is valve seals.either way it is costly to repair.

White smoke tells me that you have entered the land of "blown head gasket" Is temp normal and coolant full? If not, you are definitely there. Job is not difficult for a reasonably experienced tech, if you're not, either get a manual and follow instructions very carefully, or, bring it to a reputable shop. Parts are under 300... Don't forget to replace cylinder head bolts (they might look OK but are not to be re-used.)

'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.
