Yea, pull the valve covers and look at the rocker arms. Check the clearance and rotate it through a couple of times. Pull the plug to make it all easier. They don't make an audible click to me but I don't have the best hearing, especially at high freq.
If you don't have valve problems then you have to look at the cam/timing gear and the crank/bearings.
