If you hear a metallic rapping coming from the lower end, it could be a rod failure, yes.

You did check the oil level to be sure it's full and clean, right? .

Next thing to do is to get an oil pressure gauge rented from a parts store (like Autozone) and do an oil pressure check. Check the readings with the rented gauge versus those in (accessed through the "Basics" link below).

Tell us what an oil pressure check reveals.
