Re: white smoke out the exhaust
You will need to check head gasket. Please check the oil for coolant (milky deposition or presipitation). Also check if you loosing coolant and if coolant has oil in it.
Please kindly let me know if you need more info

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.
it sounds like the valve seals have dried out and need replacing.sitting for 5 years and not really being driven they have probably dried out.a common indication of this is when you start the car after sitting for a while you get smoke out the exhaust and don`t see the smoke when you are driving even though its burning oil just at a smaller amount.the vacume of the cylinder on the power stroke is enough that if the valve seal is bad enough oil will be sucked past the seal and valve guide into the combustion chamber and pools a little on top of the piston.then on start up the oil burns off the piston and out the exhaust,as well as while driving each cylinder that a seal is bad the engine vacume draws oil the same way and its burnt,thus you won`t necessarily see the burnt oil coming out the exhaust.you won`t hear any noise from the motor.knowing you have this problem check the oil regularly until its fixed.also check for any other oil leaks from gaskets as sitting will dry out gaskets and you may see some gaskets that may need to be changed.
