Hopefully it isn't a major problem, but white smoke sounds like you are burning water/coolant, thus either a blown head gasket or cracked cylinder liner. A compression/leakdown test will tell you pretty quick. Echoing the sentiments of others, please stop running the car or you will guarantee the need for a new motor.

If the engine is done and you decide to sell it as is, let me know, I might be interested in it.
