This is to clarify the correct tool numbers to be used when ordering valve micrometers used for measuring valve cap clearance.

There are two different tools available; one for car and one for truck.

Special Service Tool TOOL-6513-CEB is used on car engines with 11/32 and 3/8 valve stem tips.
Special Service Tool TOOL-6513-CED is used on truck engines with 7/16 and 13/32 valve stem tips.

The tools accurately measure free valve cap clearance in or out of the head. The tools are shipped complete in a wooden storage box.
