Does it happen repeatably at that RPM?

It could also be rod knock then. I was hoping not, but it is a known 'failure type' on these engines. If someone didn't put the caps back on correctly I can only imagine the bottom end not being properly assembled either.

What you can do, is disconnect one coil pack at a time. Sure it will run rough, but disregard. Rev the engine up and see if the rattle gets quieter or even disappears completely. If so it's time to open that bottom end up and investigate.
