Default Coolant Leak Help

I have a slow coolant leak in my LS1 swap. I believe the leak is coming from where the feed line is going into the top of the block. It appears to be coming out from underneath that metal coupler that goes between the radiator hose & block. I haven't looked into this too seriously yet but the coupler doesn't appear to be damaged in any way. Any ideas on how to fix this?

Nobody has had this problem? Is there supposed to be an o-ring there?

Yes, there is a small metal gasket and o ring that goes under the crossover tube connectors.

The metal coupler I am talking about is actually the one for the main feed line from the rad not the crossover tube.

If it is not the crossover gaskets then send a pick, I thought it was that as well. Its not the powersteering cooler is it?
