Valve timing diagram
A valve timing diagram is a graphical representation of the opening and closing of the intake and exhaust valve of the engine, The opening and closing of the valves of the engine depend upon the movement of piston from TDC to BDC, This relation between piston and valves is controlled by setting a graphical


Why is valve timing important?
Valve timing is an important part of the internal combustion process as it regulates the flow of fuel and air in and exhaust out of the combustion chamber – that's the part of the engine where the pistons compress the fuel and air for combustion


How do you know when valves are closed?
So you want to adjust when the bottom of the rocker is inward. If you have a shop manual it tells you which valves to adjust when the timing mark is top dead center. You don't have to turn the engine over every cylinder. In using your words, " the top of the rocker arm is out towards you" is when that valve is closed
