Question 434Motor Plants - Assistant Engineer

The correct answer is B) Cold valve clearance is measured between components "C" and "D". This is correct because the valve clearance is typically measured between the valve stem and the rocker arm or tappet, which correspond to components "C" and "D" in the illustration. The valve clearance is checked when the engine is cold to ensure proper adjustment and to prevent damage to the valve train components during operation. The other options are incorrect because A) refers to the tappet clearance, which is not the same as the valve clearance, C) and D) refer to the adjustment points, not the measurement locations.
