We would like to install a fireplace to an existing chimney that is used for oil heating a house. One story house. 18 inch internal diamater brick chimney. Chimney is in perfect location for a main floor living room fireplace install. What special precautions do we need to take to eliminate the chance of oil exhaust coming from the heater in the basement into the living room on its way up the chimney? Any suggestions on how to install into an existing chimney would be helpful too! Thanks!

I don't think 2 devices can share a chimney. Best to check with your local building department.

Can we use the existing oil heat chimney but have a separate exhaust channel/tubing/whatever within the chimney for the fireplace? This way the chimney could be used for both exhausts, but still be separate. Is this a potential danger?
Is there ANY way to make this work so we can use the existing chimney for oil heat and fireplace? Thanks!

The only way I know of that you could accomplish what you're trying to do would be if the clear dimensions of the existing flue were such that two new separate flues could be installed within, one flue for the furnace, one for the fireplace. In your OP you mentioned that the houe had an "18 inch internal diamater brick chimney". Did you mean the chimney is 18" outside dimensions, or the flue itself is 18" clear diameter. That would be a heck of a big flue for a house. But if it is that big, you might be able to install separate flues inside. The point is, in most jurisdictions I'm aware of, each of the uses has to have a separate flue.
