Long as I'm here, my 92RS uses just a bit of water and I don't find any leaks or other symptoms. It's never been real hot and has low miles. Any oblvious things to check?

You could have a slow drip out of the radiator or a hose or it could be as bad as a leaky head or intake gasket.

 

A leaky intake gasket is usually the culprit on these cars. My car, and many others on these boards have had the same problem. If you can't find a leak anywhere and everything seems dry, more than likely its your intake gasket.

 

I had a slow leak I could never find either. Then finally I was leaking alot of coolant from my weep hole on my waterpump. Replaced the pump and problem solved

 

pressure test your cooling system.
