How to measure the diameter of each intake valve and exhaust valve stem for service and repair on Mercury Milan?

In order to repair and adjust the valve, it is important to examine the diameter of the valve stems of both intake and exhaust valves at the required points. Make sure that the diameter is up to the required specifications. Otherwise, change the parts as necessary.

How should the Exhaust Valve and Intake Valve be inspected for signs of damage and wear on Mercury Mountaineer?

Inspect the stem to identify the presence of grooves/scoring, examine the valve face and edge to identify pits/grooves/scores, examine the valve head to determine burning, erosion, warpage and cracking and assess the valve margin to identify wear.
