I was priming my turbo the other day and while I was cranking the engine, I noticed a little bit of smoke from the top of my valve cover. My car was being jumped by another car at the time since the battery had been a little low. I had my dad crank the motor and the middle spark plug wire holder on the valve cover was glowing red hot at the point where it touched the square metal block next to it. Bad ground or what? Thanks for the ideas.
