I need a diagram for the timming belt for a daewoo nubira 2000

I need help. opel 16v ecotec motor.. help with cam timing.. how should the cams be set?

What model ?? 8 valve?? 16 valve?? petrol ?? diesel?? .Remove np one spàrk plug and put a long thin screwdriver into hole and turn engine till the piston is at the top and then look for timing marks ,if you still cant see them paint the cam gear .with a couple of spots of white paint ,the lower crank mark it when the keyway points at the top of bottom of the engine.If i remember rightly these opel engines have the timing mark as a white line on the belt .But mark it anyway and always rotate the engine 360% by hand to make sure the valves clear and you have it right
