White smoke out the exhaust

Any check engine light? Have you checked coolant level? This has all the symptoms of a blown head gasket

White smoke is an indicator of moisture. All cars will show water vapor at start up as heating up drives moisture out of the exhaust system AND the combustion of fuel produces water vapor. Until things warm up, slight white "smoke" can be seen coming from the exhaust. If there is a lot of smoke, more than a normal car starting up, that could be radiator fluid leaking into the combustion chamber. Is the radiator fluid level going down? If it is, that it could be a gasket leaking.

White smoke is condensation from a buildup of water from within the exhaust system - if it was blue smoke then it is burning oil ... let car sit for a few minutes and take the dipstick out - wipe it clean - then re-insert dipstick - take it back out and check level against gauge at bottom of dipstick if you think you may have overfilled the oil

White smoke on start up can be lots of raw fuel

White Smoke any other time is a failed Head Gasket
& major repair

Check to see if your coolant goes down in the plastic
container overnight

Where is the smoke coming from, Is it coming from the exhaust of engine bay. Colour of smoke?

Regarding 2001 audi a6 quattro 2.7t....i was driving to work the car was fine then white smoke starting coming from under the hood and tail pipe. i stopped veilce and alot of oil was dripping from front of car. I towed it home and i looked under the hood and there was oil from valve cover gasket. i let the car sit for a few days, had it running again for a good hour and no white smoke was coming out. I removed the valve cover and gaskets are all bad. i want to know can the valve cover gasket leak cause the white smoke to come from exhaust pipe?

It basically could be because it has been sitting for so long, but if it keeps on having smoke come. Out it can be a head gasket. Try to let it run if it stops your good if it keeps blowing smoke take it to a shop

White exhaust smoke usually comes from coolant in the cylinders, indicating a cracked head or blown head gasket. The best test is to pressurize the cooling system, then remove the sparkplugs and look for moisture in the cylinders. Turning the engine over with the plugs out will spray a mist from any cylinder with coolant in it.

time to trade it in quick for a new one ,this is a head gasket ?? and its water seeping into piston ,could be a manifold gasket ?? but its a big job and with dealer prices ?? trade it in quick
