Ouch. Sounds like a rod knock to me. It's got that distinct internal noise, so it couldn't be the balancer.

How many miles are on the engine? How many miles have you owned it? Is there metal in the oil?

Rod bearing. That engine is on its last few miles. It's either going to throw a rod through the block, or seize up completely. Sorry to say.

I think it would be a good idea to at least change the fluid and filter, and look for signs that the transmission might soon fallow the engine. It wouldn't be any fun to have to replace the engine 2 months after the engine.
