White smoke is coming out of the tail pipe when first started and idling but goes away at road speed. when the car is shut off and restarted smoke comes out again

Leaky injector

what smokes. we are blind here.
you must stay.

1: end of tail pipe smokes
2: or, with hood up the exhaust manifold smokes due to oil we dropped there. (common on much service)
and what color is it.?
from where.?
tail pipe can do 3 colors
white goes away fast ,called steam.
white stays way too long called burned oil smoke,
and black (unburned fuel) and smells like gas..

A heavy presence of white smoke from the tail pipe is usually caused by a bad headgasket. If this gasket is bad, the vehicle may run rough as well as overheat.

what kind of smoke by that I mean what colour is it and when does is happen under hard acceleration, at idle, when first started, under light acceleration, idling a long time? blue smoke is burning oil, white smoke is burning coolant sometimes accompanied with a sweet smell, black smoke its running rich. those are the basics.

What are you asking ?

Sounds like the motor is gone mechanically

smoking from where?, front of car, middle or tail pipe.


is this your first car, or first car and first winter (white steam?)
there are 3 kinds of smoke
black , carb flooding (ask why)
white, oil, burning, take for ever to go away
white steam, goes away fast and smells like Antifreeze, sweet and nasty.

and all carbs smoke black in the tail pipe end, when cold, unless
you very carefully tune the choke plate.
so do tell? what?

Possibly a blown head gasket, letting coolant into the cylinders to be burned. White smoke is usually coolant burning. Have the engine's compression tested to verify.

I gather you are sure it is smoke and not water vapour from the car warming up? Cars can run rich at start up until it warms up (automatic choke). You may have also overfilled the oil a little this can cause some burning through breathers. Unless it is excessive I would not worry too much about it - keep an eye on your oil and coolent levels.

You may have a blown head gasket,how is your coolant level?

U have a blown head gasket the white smoke is burning coolant
