What happens when you float a lifter?

Billy,

You can get a broom stick and put one end of it up to the valve cover and the other end to your ear and hear where it might be coming from.

Move it all along the valve covers until you hear the tick, (or noise), get louder.

This should give you an idea where to begin.

Parts stores sell tools that do this but it has worked for me in the past.

Either way it sounds like you are going to have to pull off the valve covers and do some checking.

Hmm, i saw my dad and some of his buddies doing this in his shop once, i didn't know what the hell was going on till he told me.
