I have an MSD 6AL and blaster II coil and a stock distributer on my 440. While the car was running I noticed the positive teminal smoking. It almost looked like it had a blue ingition spark coming out of it not going into it. I tightened both terminals ( + and - ) and started the car but it still does it. Now I see what looks like oil or burnt plastic coming out of the top of the stud on the + terminal. Any ideas ?
