2002 330xi Engine Rapping Noise (video)

Below is a link for some audio I recorded of the noise:

It only happens on a cold start and the frequency increases with RPM. After hitting 2,000 RPM or warming up, it goes away.

After searching online/here I'm thinking it's the hydraulic lifter(s)? Can anyone confirm or tell me how to diagnose this for sure? Any links for parts or a DIY would be helpful!!!
