Extremely loud taping noise in engine
 

I previously had an engine problem where the lifters and headers were replaced in my engine but this noise sounds different and is 10 times louder. I am unsure what it is.

Its a 2008 3.0L X5 only 57K miles on it.

I took off engine cover and theres a spring that seems to be in sync with the noise as the cam turns but I cant tell if thats what is causing it. I uploaded a video to youtube with the noise.

turn your steering wheel and see if the noise changes, I had same noise but it was the power steering pump knocking because of loose belt.
