Towards the front of the engine?

Sounds like timing chain.

Does it rattle when you apply brake?

I don't remember which side it's on, but I got a rattling when the jack under the rear seat came a little loose... No all the time either.. So it could be that?... Unless you're talking about something up front...

There is a heat shield on the catalytic converter, it could be loose.

Leaking exhaust can make some kind of rattling sounds. Might check that.
