Sounds like your lifters are bleeding out when the engine is shut down. It goes away because they pump themselves back up when engine runs. They can rattle while running as well. I would get some engine oil treatment and run that in your oil. A good brand is Seafoam run that in your oil and that should clean out your lifters.
