I have a 85 grand prix v8 an I'm having problems!! When I start it smoke comes out the exhaust for a while then it stops. Also, when I drive for a period of time a tickin noise starts an the more I accelerate the louder it becomes. It did this for a while because I was in the middle of a traffic jam an it eventually started smoking so I pulled over an cut the car off. I put antifreeze in an tried to start it up an I guess it was too hot at the time because it wouldent start but after a while it eventually started but smoked again when I stopped at a light. This is a lot going on an I need help!
