MODELS RATTELING SOUND

2006 Mazda Other

Engine Mechanical problem
2006 Other Mazda Models 4 cyl All Wheel Drive Manual 11000 miles

I have a mazdaspped6 2006 2.3 turbo. Lately when I start the engine there is a ratteling sound (like Marbles in the valvecover) for about 1 second then it goes away. When the engine sits for more then 20 min then you start it, ti rattles again. I change my oil every 500 miles castrol 10w-30 full synth. What can it be? Timing chain tensioner? The vvt actuator?
