2003 engine rattle - knock on deceleration

I need some help. I have a strange engine rattle on deceleration only. It sounds like a rocker arm is loose. The rattle is random. It can be heard when slowing down with the windows down. The sound is not the same each time.

I checked the valve clearances yesterday and all are in tollerance. Nothing loose. Thought a lifter might be loosing pressure.

Any Thoughts???
