my 91 toyota corolla has tail pipe smoke and condensation when cold started.Whats the problem and the fix?

Question

car has 133k miles takes more than 15 mins to warm up,has rough idle

Answer 1

Hello if it is only smoking at the cold start up then that is normal, its not really smoke more less steam from cold engine, will be more so in cold environments and really cold mrngs etc.. if you are always getting a white smoke from the car eben after warming up then have it checked out that is most likely oil smoke,one prevois answers says blue was oil smoke well it may be a whitish blue smoke but not blue, never seen actually blue smoke and i have been working on cars and engines for a long time, at 133,k miles i would suggest having plugs /and all wires changed, for as warming up taking 15 minutes the older the engine the longer it will take to warm up just like a old man 20 yr old warms up adapts much faster than a 70 yr old, have the thermostat checked/changed, if you are in a cold environment then 15 minutes could be very normal for a new car as well . many things can cause oil smoke all the items mentioned below in orevos answers, blown head gasket, valve cover gaskets, etc.. or the engine could be wore out, any mechanic should be ablke to check it out for you, its a Toyota so if you have tooken care of it i wouldnt suspect any major problems . Toyota builds fine products, 133 k miles is alot but ive seen as much as 280,000 miles on toyota engines with no problems , Good luck..

Some (white) smoke is considered normal as long as you are not loosing any antifreeze.
Smoke colors: BLUE= Oil WHITE= Water (coolant) BLACK= Too much fuel (rich mix)
With high mileage, you may want to consider changing the spark plugs as preventive maintenance. Plugs get old and wear so you need to change them. If (after changing the plugs) you notice EXCESSIVE smoke coming from the tail pipe, you may want to have a technician do a compression test or cylinder leakage test. These tests can tell you if you have major problems developing.

FIRST i might enable THE ENG IDLE AND seem decrease than THE HOOD to work out the place it incredibly is COMING FROM SEEING the way it STOPS AFTER WARMING UP i might think of it incredibly is a CRACK OR GASKET subject in case you think of ITS A CRACK AFTER SEEING the place THE WHITE VAPOR IS COMING FROM purchase some SILVER SEAL AND positioned IT interior the RAD do this whilst THE ENG IS chilly USE 2 SMALL packing containers not ONE IF THIS STOPS IT it is going to basically artwork FOR a quick time LIKE perhaps 2 MONTHS IF IT gets WORSE IN warmer climate THEN i might GET IT CHECKED AT good restore shop they might examine THE WHITE SMOKE AND inform you IF ITS RAD COOLANT AND which will inform you plenty approximately WHAT the project is nice success JFB

Answer 4

The smoke and condensation may be normal on cold starts. As for taking a long time to warm up, look at the thermostat, it may be bleeding through and not staying up to temp.

Once the engine is warm and you still have water coming out, and you are losing coolant, then it may be a head gasket problem. good luck

Answer 5

If a cloud of smoke comes out of your tail pipe after sitting over night usually its your valve stem seals on the cylinder head that are leaking oil. Oil seeps through while sitting and when you start vehicle all that oil burns out causing the smoke. The only way to fix that is replacing them which is pretty difficult wouldnt recommend doing it yourself if you dont know what your doing. I would recommend taking it to a dealer to get it looked at or if you like a private mechanic.

Answer 6

It is most likely a few things wrong with it, if its fuel injected then you have bad injecters and possibly a voltage problem to them. change your spark plugs and inspect them. if any are more carboned up then others then those are the cyclinders that are giving off the tailpipe smoke you see.replace the distributor cap and rotor too. check for faulty plug wires.also treat your auto to a little octane boost,give it 10 gals. of mid-grade fuel.(you can mix low grade and mid grade fuel.)

Answer 7

probably needs a valve cover gasket. I have the same car with 140,000 and mine needed to be changed when the engine started smoking. another way to tell is if you're losing fluid.

Answer 8

you got an OLD car. that's the prob.

just like your aunt tilly, everything has to die after a while.
