I need help diagnosing a knocking sound in my Chevrolet 250cu 4.1L. I have tried pulling spark plug caps to determine if it is in one of the cylinders thinking it could be a wrist pin and this had no effect on the noise. The sound comes from deep in the engine. The knock keeps time with the engine.

Do you
have the same problem?
