Ahhh... but it does. You not only get the lifter type ticking noise, you can feel it when you put your fingers on the valve. It's the check ball. It does it on a cold start up then gradually disappears as the engine warms up a bit.
If the OP is reporting this on a 2000, then they did nothing to isolate the sound at least through the 2002 MY.
