title says it. i had an issue with some noise coming from top, figured it was the timing chain guide, took it off.

but during the course of this, a nut fell in timing chain area, and i had to take chain off to get to it. now i need help getting my timing down.

five marks on crank pulley, which is supposed to align with mark on block? how are cams supposed to be aligned? my chain has two marks on it, along with a gold link. i assume gold link aligns with marker on idler pulley, and the other two marks align with dots on cam sprockets?

PLEASE help...
