Couldn't change the noise killing cylinders via spark plug wires, and seems repetitive. Not to mention, comes and goes?.. Glenn, I've had exhaust leaks that made a slight serious sound before and agree they can be a cause for concern. However when you listen with something touching the block to ear, it's definitely a low frequency metallic sound from deep in the engine. The above said, if I discover your suggestion is spot on, I'll buy the boiler makers as we toast to your psychic abilities! RonR
