I have a running motor that I took out of my truck. It does smoke on start up and when you leave an intersection. My Wife wouldnt drive it with it smoking so we put a new one in. I bought the truck with it smoking, but chose to put a new motor in instead of fixing it. I drove the truck a little over two hours when I bought and put a little over 1k miles on it with no issues before taking it out. Located in Winchester Tn. $600
