1997 Pontiac Grand Prix engine smoking and leaking

Please put some punctuation in that huge sentence. Which of these is correct:

"I would drive for a little while and my car would start to smoking."

"I would drive for a little while and my car would start to smoking after turning off engine."

"my car would start to smoking after turning off engine."

"after turning off engine it begins to leak."

This hasn't happened before? Really? The same can be said of all problems on all cars. You haven't provided any clue as to what is smoking or what is leaking. Is the smoke coming from under the hood, by one wheel, or from the dash? Where do you see something leaking? Can you see if the fluid has a color and whether it feels oily?

The smoking and overheating, if related, could potentially be relatively minor but if you continue to run the engine that way it could become very serious and expensive very quickly. The best thing to do is have a mechanic take a look at it.
