It sounds like a rocker arm has gone bad or you have a broken valve spring. I would remove the valve cover and with a flashlight check the springs and rocker arms. If you upload a short video of the noise, I can tell for sure. Here is a guide that can help, and I have included how to remove the valve cover in the images below.

Try to see which side of the engine the noise is coming from. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
