White smoke usually indicates a blown head gasket or cracked head, watch the coolant level or check for oil in coolant or coolant in oil, might consider taking it to a shop you trust and have it block checked.

Good advice. There are a few things that can go wrong to cause smoke at operating temp but instead of throwing money at it, I'd have the engine evaluated first as suggested.

Pure white smoke or could it be a whitish light blue smoke? Does it smell sweet or like coolant or more like oil/gas mixture? Does smoke only just puff out then stop with no smoke after accelerating? If no loss of coolant I would lean towards valve guide seals. With the age of your car they are probably hard and brittle. Some say they will only cause smoke at start up but that is not correct. They can also do it just as yours does.

Same thing, if it smoking out the tailpipe then have the checked for blown head gaskets. If it's in the engine compartment then you have a coolant leak, most common if it's not the hoses, or the radiator side tanks leaking, is the water pump.
