The quickest way to tell is to remove the vaccum hose from the top, fit a
short piece of tubing to it, and suck! This is assuming you don't have
available to you a proper vacuum testing device. Not only should there be no
loss of vacuum, but the small piston in the center of the EGR valve should
move freely up and down.
Cheers!
