Does your idle still lope a bit after you released the throttle? Mine does the exact same thing. It will lope down to 600rpm, and then come back to normal idle.

Is not the Vanos. I had the Vanos replaced a year ago, and I know that sound. It is different to the vanos noise. Revs don't dip after reving. It just sounds like a metalic tapping sound, then disappears agin. I was thinking it could be the timing chain? Do you think the chain could make that type of noise, or is it likely to be a lifter?

The hydraulic lifters making sound on a cold engine is quite normal. Oil drains out of the lifters gradually when the engine is shut down. If the noise disappears when you give gas or when it is warmed up I wouldn't worry about it.
