300SE Thermostat Bypass Line

I have a leak where the head portion of the thermostat bypass line connects to the head. It is an approx 1.25" dia aluminium pipe about 4" long. Talking with 3 dealers and 8 indy's in the local area no one has ever seen a leak in this spot. They also do not know how it is connected. 2 of 9 guess that it has pipe threads and is screwed into the head. The others either won't venture a guess or refer to the fiche and say start looking for a new head. Any experience or ideas for solving this leak is seriously sought, just changed the head gasket, really would like to solve this without pulling the head again!
