Question about 1999 Ford Taurus
Began backfiring thru intake, changed O2 sensor(chewed thru) on way home it began blowing white smoke and 3 miles later, it quit. Did I just blow the head gaskets? What did changing the O2 sensors do to cause this, or did it? I don't think so, but the car runs great, just missing and backfiring. Fixed backfire, not sure I want to put plugs in it if the gasket just blew. Thanx.
White smoke is usually steam which would indicate a blown head gasket or crack in block. Hope it's something easier.

You said you FIXED the backfire? Car runs great? If you blew a head gasket you'd be running on 5 cylinders probabl y.
Now if were running really bad,I'd say it could be fuel pressure,but you say it isn't running bad.
If it's a head gasket, you'll usually see bubbles making their way up into the expansion tank continually.
Run the codes and if it's showing cyl. miss,pull the wires one by one from the coil pack to see which one DOESN't make an rpm difference.Use soe insulation between your fingers and the spark plug wire or you'll get a shock.
Make sure you post back even if you fix it so we all can learn something? don-ohio (:^)

SOURCE: my truck blows white smoke
There are two differnt reasons for black and white smoke coming from the tail pipe.
Black smoke means fuel runs rich (car getting to much gas). Check fuel pressure/air filter.
In some cases the white smoke means car is burning oil or transmittion fluid. Have tem checked/replaced.
If you can feel a smelly smoke it can be catalytic converter.
In a worsest scenario if car blowing white smoke it can be engine coolant is getting into an engine cylinder from a bad head gasket ,or a warped/cracked head. So you need to keep your eye on coolant level and check your engine for overheat. Also might be good to check your oil for traces of coolant (on a dipstick it would be a milky substance mixture of oil and coolant).

black smoke is fuel white smoke is oil. change your spark plugs to a hotter plug and run with some hpr 50 engine oil or somrthing nice and thick

It does not sound good its possible with that high mileage the engine has internal damage.Also if you did not have the cylinder heads checked by a machine shop that could pose a problem also.We have replaced so many of those engines that i could not tell you how many ive actually replaced.At this point i would suggest that you install a low mileage salvage engine if you want it to be dependable.
