If you suspect a rod bearing, start it up and, one at a time, disconnect or short out the spark plug wires to see if removing one wire makes the knock go away. If so, it may be time to drop the pan and check further.

PS - did the knock occur when the engine was under load, or at an idle? Light metallic knock or a heavy, thud type of sound? Have you ever had the pan down to clean it and the oil pump intake screen? IMO this is something that should always be done when first putting a car into service unless you know it was recently done.

PPS - might be helpful if you could post an audio file of the sound.
