What causes white smoke from the exhaust and also a loss of power when you try to pick up speed and poor acceleration?

You probably are loosing coolant also. You have a blown head gasket. Have the head checked for cracks when you have it off.

AnswerCheck compression in all cylinders. If the head gasket is blown, there may be 2 adjacent cylinders with lower compression than the others (20% difference is ok). It's possible the compression is within the limits on all cylinders. If this is the case, remove all spark plugs and rotate the motor by hand (place a socket on the crankshaft dampner bolt and turn the dampner clockwise; look for coolant spilling out of any spark plug hole). If coolant comes out of spark plug hole, suspect head gasket failure. Is the temperature gauge reading high? Or is the temperature gauge rising and falling? If so, definitely suspect head gasket failure. Get a Haynes Manual and do the job your self; big money saver!!! AnswerBlown head gasket. You'll know which cylinder(s) have coolant leaking into them by the color of the spark plugs - they'll be white/chalky if they've been subjected to coolant in the cylinder.

Most importantly, do not drive that car until you get it fixed! The coolant is washing all the oil off the cylinder walls and you'll destroy the rings in that cylinder, not to mention the damage to the cylinder wall. That gets real expensive, fast.


Head gasket could be a problem, have it checked by a shop its a cheap test all they do is place a tester with blue liquid in the radiator. If it turns green it is detecting gases in the coolant system from a blown head gasket. It could also need a valve job usually you can smell the difference between coolant or oil. which fluids are you losing coolant or oil or both? Oil can pass through worn valve seals and burn out the exhaust valve causing white smoke. Head gaskets are expensive to repair unless you perform the task yourself. You have to enough tools to repair and a machine shop will have to smooth sealing surface and any other worn parts need to be replaced.

Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.

White smoke is water vapor (or coolant) in the exhaust, the black smoke is the (normal) over-rich condition at WOT (full acceleration) White smoke can also be unburned fuel, generally seen on earlier, non-electronic engines that are mistimed.

White smoke means head gasket, cracked head or equivelant.
