Believe me Steve, I certainly don't relish the thought of getting the head done (regardless of that pesky oil leak that I've had for a while).

I'm going to look at the leak a little closer in the morning when I have some time. I would like to find you correct.

By the way though, aren't you referring to the heater return line? Because if so, it's on the front of the engine, driver side. My coolant leak appears to be at the rear of the engine, passenger side. Is there another heater hose with an o-ring that I'm overlooking maybe?
