I heard white smoke could be coolant leaking into the engine and black smoke is burning oil...Hate to say it, yours could be both if a head is cracked.

Not necessarily. I had no smoke, but a lot of oil burning. I changed some parts in the engine - oil gaskets I think. 700 euro job. That's about a 1000 usd.

White smoke in the exhaust is caused by oil and water mixing somewhere in the ignition cycle. It can be as simple and cheap as replacing the head gasket or a nightmare and expensive as a crack in one of the cylinders or the head itself!
