Clearence for the valve is measured when the lifter is off the cam lobe and is rubbing on the round surface opposite the lifting lobe. For example,Let's say we have a one cylinder engine, when the INTAKE valve is open any amount, the EXHAUST valve would be completely closed. Therefore clearence can be adjusted on the exhaust valve. Turn the engine until the exhaust valve is open and the intake valve can then be adjusted. The intake valve does not have to be completely open to adjust the exhaust valve on the same cylinder and Vice-Versa.To sum things up: If you place a dial indicator on the valve tappett and turn the engine over, the indicator will not move until the camshaft lob lifts the lifter, thus opening the valve. Hope this is a good explination.
