Question about 1992 Lexus Sc 300

1 Answer

Blowing smoke out tailpipes,white to light grey,

Vehicle: 1992 Lexus SC300 - Blowing smoke out tailpipes,white to light grey, smell of fuel somewhat strong. Fuel pump will not shut off when ignition is on, but engine not running,could this be a pressure regulator issue ? To get engine to start I have to press the gas pedal so it will not lock up, like a "hydro lock" problem. I am sure,but not certain, it is not a head gasket due to water level staying full. Engine has very rough idle and driveability ,even after full tune up, cap,rotor,plugs,wires,fuel filter. Check engine light is not on,and does not come on while the car is running. O2 sensors & alternator have been changed recently also.

    The engine vibrates more than usual always. Right when I start the car the vibrating starts .It smells like something may be burning. I recently changed oil and trans fluid. The check engine light is flashing

Light bluesmok coming from tailpipe


hi
light blue smoke would suggest a small amount of oil being burnt in the cylinder. could be a valve stem seal, or a faulty oil control ring on a piston.

grey/ black smoke would suggest excess fuel, usually due to a clogged air filter.

white smoke would suggest water being burnt in the cylinder from a blown heat gasket. this would usually smell slightly sweet and sugary from the antifreeze/summer coolant in the water.

any smoke from the tailpipe should be checked as the emissions could be out of limits as well.

check the spark plugs one at a time.
blackened dry plugs would suggest excess fuel.
black and oily plugs would suggest oil in that piston.
it should give you an idea of where to start looking for the fault.

What is the diagnosis for white smoke smelling like gas coming out my tailpipe on a 1992 lexus es 300?


With out seeing the car or the smoke, I can guess that you are leaking water into the combustion chamber. Have you noticed any unususal water loss or oil loss? Most likely cause for this is a bad head gasket or intake gasket.

White smoke and a smell of fuel


The white smoke is from anti freeze. The smell of gas in your oil is probably from the same cause. I do beleive you did not clean the milled ares good enough before installing one or both of your gaskets. Just in case you did loosen one of the head bolts up for any reason....One bolt I do beleive on the right front bank of this engine has to be also sealed before re enstalling it for coolant will pass through it if not sealed

Cannot find the carburettor - where is it please?


if it's a 2001 model it is fuel injected which means it doesn't have a carby. the white grey smoke is burning oil which means you might want to keep an eye on you're oil level but the strong smell of fuel and lack of acceleration could be caused by a fuel leak somewhere

'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.
