White smoke indicates oil is getting into the combustion chamber either by worn piston rings or worn valve guides.
A compression test on all cyclinders can determine if the pistion rings are worn, The garage mechanic can carry out this test for you.
replacing piston rings is a major engine overhaul, other worn parts should be replaces at this time too. A refurbish engine swap may be a cheaper option unless you are can DIY.

SOURCE: white smoke coming from exhaust when accelerating

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

SOURCE: 93 lexus es300 overheating

with the engine running at operating tempature the electric cooling fans should be running. if they are not this means that one or more of the sensors could be faulty. either the coolant temp sensor on the intake manifold or the one on the fan assembly. also there could be a bad relay in the power distribution box under the hood. this would be a good place to start. with the engine running at tempature the fan should be running if it s not then go to the power distribution box and switch the relay of the a/c clutch with the radiator fan relay if the fans kick on then replace the fan relay if the fans do not kick on you have either a faulty temp sensor on the fan or the fan itself is bad. if the fan is running properly then it's a mechanical problem mostlikely your water pump is not circul;ating the coolant. to check this remove the radiator cap( remember if the vehicle is hot do not remove the cap it's under pressure ) touch the upper radiator hose if it is hot then the thermostat is open and it is ok if it is cold then replace the thermostat.if the radiator cap is removed and the vehicle is running you should be able to see coolant movement in the radiator if there is not replace the water pump

SOURCE: how is a tune up for a 93 lexus es300

replace spark plugs, spark plug wires, cap, ignition rotor, air filter, oil change, transmission flush, transmission filter&gasket .. That should do it.. It'lI be good if you could check your timing as well.. do this tune up every 15-20 thousand miles and oil changed every 3000 miles, depend on how much you drive it.

Smoke coming out the tailpipe 1992 lexus es300 white to grayish in color have no knocks starts on a dime


Do you have to ad coolant very offen? White smoke may be an indication of engine coolant getting into the compression chamber.Sometimes you can remove the oil filler cap and look at the underside of it for a white milky residue
if its there you should have a shop look at it and take a compression test.Hope this helps.

White smoke means water is getting into the engine from teh coolant system. Likely that your engine cylinder head has a crack, or head gasket is bad

White smoke usually indicates water in the oil.
You should pull your oil dipstick and see if you see water bubbles on the stick

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.

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.

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).

'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.
