If you have a slant six, you have a Dodge. That's a problem.

Seriously though, I imagine you have an inline-six, and metal on metal noises can be anything from a loose fan to a spun rod-bearing. Is it clunky, or scrapey sounding? Does it go away when you give it fuel, or get louder? Are there metal shavings in your oil, or on your drain-plug? Is there water in the oil, or vice-versa? Does anything feel loose?

Take a stethoscope (with a rag wrapped around it), or a piece of rubber tubing, and listen to different places around the motor, to see if you can determine where it's coming from. That's often a good start.
