Since I am totally screwed on removing the sheared off glow plugs, and drilling out did not work. I now have to pull the head.

Upon removing the valve cover, and taking a long look at the timing chain, I have come to the realization, that before I fool with the timing chain, I need to find the neutral position for the cam. Anyone have any ideas where zero is at or should I say the safe position to undo the timing chain.

Any other wisdom, before I screw myself any worse than I already have so far, please pass it along.

Thanks,
