Today in the morning when I turn on my car, white smoke was blowing from under my car and I know that in the morning is suppost to but not that much.. so I let it go cause it was raining yesterday. then after about 45 min when I got to the valley I went in to a bank to get some money out,but after I turn off the car there was some loud ticking coming fromt the hood.. I know it normaly does this put not as loud. When I turn on the car again there was that smoke again and this time was more.. then in the morning.

I pull over on the next block and i turn off the car to see if it would do it again.. I it has not done it since the second time. I dont think is coolent cause it doesnt smell like coolant, it not oil cause is not dark.. the only think I can think is water but from where.. the only thing I chang this weekend was the PCV valve.

Kind of long can some one help
