Need Help - New problem -Blown Gasket

My car has developed a new problem. I have been driving it for about 6 months now, and yesterday I noticed smoke coming out of exhaust. It was while driving on the Hwy traffic had come to a standstill so after the stop when traffic strted to move I looked in the rear view mirror a noticed some smoke behind my car. I was surprised at first because it was first time I seen it smoke .
Now I kept on watching my rearview mirror to see if more smoke was coming out but no, it was ok. Again I stopped at a traffis light at the exit and there was no smoke but when I started to move there was a big plume of smoke again.
And the same thing happned this morning too while coming to work.

I heed help, please, can someone tell me what is going on, what should I do?



Ok the mechanic diagnosed that the head gasket is leaking, he took the Spark plug out and it was wet & sort of greenish color. He thinks that coolant is getting in through the blown gasket. to replace thagsket, may be also machine the head, he has quoted me $1600 dollars (Canadian). I am not sure if this is the best option, a friend had suggested a rebuilt engine. How much does a rebuild engine cost and where can I buy one. Or if it is advised to go for repairs what else should or can I get done while the head is off.

If the automatic trans is overfilled it would smoke because the excess vents onto the hot exhaust. After 30 min. of driving, check the fluid level, car idling in park. Should be just below the full mark. Otherwise maybe valve stem guides worn.
