I was driving my car along the interstate. I was going like 68mph. The car just died on me. I hadnt gone but about 20 miles. I know that my ignition coil was going bad. bUt I have no any other problems wit it. Has a rebuilt head, stock everything else. And when I started it up, it would shoot smoke out of the valve coverlike an exhaust manifold. It still cracks, just runs terrible. So I had it towed(this was on thanksgiving btw). I was want to get some ideas of what might be damaged, or caused this. Anyone?
