Is the knock coming from the engine? Is the engine oil clean and full?

Okay, my not being there to hear the noise makes it hard for me to diagnose the problem. It takes a trained ear to recognize different sounds. It could be a rod bearing, main bearing, cam bearing... the list goes on. Because I am not there, I have to recommend that you let a tech hear it and tell you what it is coming from. They shouldn't charge you because it will only take a minute to tell.

Once you find out, let me know and I can hopefully give you some options.
