Does it sound like it is coming from the top or bottom of the engine?

Could be some valve lap, IDK.

Does the knocking go away after you rev higher?

Checked the oil? Sounds like you may have low oil pressure, that can sometime give the RPM dependent noise like that. Very hard to say without actually hearing it.

How much mileage on it?
