We have not ran the car in a while a little white smoke

I do think you have a leaking engine cylinder gasket or a cracked cylinder head.

A little white/blue smoke at startup is usually an indication of valve seals leaking a little. If it's only at startup and goes away, it's not a big problem - keep an eye on the oil level in the crankcase (dipstick).

If it's dense white smoke, and continues for up to a minute or so (or longer), you may be getting coolant into the cylinders - head gasket or worse problems. If this is the case, you may want to have it checked for contamination of the coolant by exhaust products.

Sounds like you have a coolant leak at your intake ,check your intake air breather hose that connects to throttle body for coolant

white smoke is a blown head gasket [white smoke burning anitfreeze]

so , you ran it out of gas after it sat for a while.
the question is .... what?
where do you put the gas in ?

Depends on how much smoke. A little puff that goes away quickly is no cause for concern the flat six engine does get oil deposits under the piston skirt when parked and is considered normal.

Excessive smoke (fogging for mosquites) indicates a failed oil \ air separator. Confirm by removing the oil fill cap with the engine running - if the vacuum tries to **** your hand into the oil tube, your separator is a goner.

Not excessively difficult to replace yourself. The part is about $300 and you can replace it in a couple of hours, it is located at the rear of the engine, passenger side, top.

Water vapor coming out of the exhaust at initial start-up is normal; that is condensation that collects when the engine is not running. White smoke at start-up depends on a couple of things. Tell me, where do you live? When the weather is very cold, all engines will emit steam (white smoke) when they are first running; this stops after the engine has been running a while and is warm.

In short, if this is only happening at first start of the morning and goes away over time, there is nothing wrong.

If, however, the "white smoke" continues and never stops, you may have a blown head gasket.

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.

first question is it smoke or steam ? if if ligers in the air behind you as you drive with little dissipation or if its steam it will dissapear more quickly . either way , head gasket is first . once saw a car do that excessive engine oil put in by owner . giant flumes of white smoke . if you ever want a true smoke scren to get away then adding about 2 to 4 quarts of oil extra . man it is something to see
