Knocking noise on passenger side of engine?

It sounds like it could be a camshaft follower which are common. Can you please shoot a quick video with your phone so I can hear the noise? That way I can tell for sure what's going on. You can upload it here with your response. We need to hear the noise, so we know which direction to go to help you fix the car. It takes time to upload so please be patient.

Here is a guide that can help in the meantime:
