Abstract
Valve lifts are measured with a reference engine assembled correctly, at at least two crank angles, and the relationship between the crank angle and the valve lifts is memorized in an arithmetic unit. Thereafter, the crank shaft of an engine, the valve actuating system of which is to be examined, is indexed at the above-mentioned crank angles in the assembled state of the engine, and the valve lifts are measured at these crank angles. The measured data are delivered to the arithmetic unit which performs an arithmetic operation to determine whether there is any abnormality in the valve actuating system and to make the display of the result of the determination.
