well last night i was repainting my valve cover bronze since it was kinda dark out side i stoped and then i finished it today so i didnt see that on of the center bolts the one that you bolt the valve cover on and it also hold the sparkplug cover was welded cuase it was broken before so what ever i keep on tighting bolts and wamm it broke i was wondering how much or does anyone have an extra on of these bolts layoing around it hold valve cover, spark plug cover, and on the inside looks like it hold a little thing thatholds cams in place.
