Hi,
The most common cause of excessive white smoke from the exhaust is engine coolant entering the combustion chamber. The cause is likely related to a failed head gasket.
Take a look through this link first:

If you find the head gasket is bad, below I attached the directions for the removal and replacement of the cylinder heads. You will first need to remove the valve covers and intake manifold. I included the directions for that as well.
I hope this helps. Let me know if you have other questions.
Take care,
Joe
