So i started the e34 540 after about a week of non-use. Before i had put it to rest the week before, I had noticed a horrible electric buzzing sound (like the kind in the movies where a power line is on the ground zapping things); I had also known that the car has a bit of a valve cover gasket problem and they need to be replaced.

Anyways, I started the car and heard a horrible ticking noise that was now accompanying the electric buzzing; i gave it a slight rev to about 2000 to see if it would go away but it got worse/faster with RPM; i need to move the car about 10 feet so i did so and a slight bit of smoke came out of the hood... I quickly turned it off; anyone have any suggestions?
