White smoke is either steam or a huge quantity of unburned fuel, both of which is a potentially serious fault and in the case of petrol or gas can be dangerous, less so with diesel.
Steam is caused by coolant ingress via head gasket, cracked head, block or sometimes by an intake manifold or gasket.
Large quantities of unburned fuel likely to be an injector stuck wide open.
I strongly suggest you don't attempt to drive it and ask an experienced person to take a look.

Hi,
Sounds typical of head gasket failure.
With this you get oil into cylinders / water into cylinders, burning oil, loosing water - but no leaks. "boiling" of radiator and overflows.
Check your coolant and oil levels - they will be low.
Get a few quotes for a head gasket replacement - and timing belt change, as it has to come off when you do this anyway & no sense putting an old one on - they often snap if retensioned.
If this solves your problem, please take a moment to rate as Fixya! thanks.

Check the fuel pressure regulator. It should have a vacuum line attached to it - disconnect the vacuum line and turn the ignition on - if fuel come out then that's your problem. DON"T do this while the engine is hot or you could start a fire!

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

Hello There
White smoke when first started is normal. If white smoke continues you have an internal coolant leak, i.e., cracked head/blown head gasket.
Black smoke is caused by a rich fuel condition.
Blue smoke is caused by oil consumption.
You need to check your oil cap for yellow/white gunk on the cap if you have this then this is a sign your head gasket is cracked. Check to see if your radiator coolant level is down this is also another sign.
Hope this helps. Please don't forget to rate me.
Many Thanks

The most likely cause is a blown head gasket,but it could also be a warped head,was the motor overheated prior to the problem starting? The white smoke is steam,check the underside of the oil fill cap and dipstick for a grayish brown residue,check the coolant for a low level and oil conatamination,either of these conditions verify that a head isn't fully sealed.Unless your moderately skilled mechanically this a job to be done by a shop.A good shop will perform a leakdown test to verify this.

Hi Sheila Clark, can you get a piece of a4 paper and put it in front of the exhaust pipe when the engine is cold but just started up running. See if you see any oil on the paper ?
