On the back of the thermostat housing (3400)?

I see there is a rubber o ring but is that it? It popped out on me.

There is supposed to be a flat bracket welded to the pipe with the O-ring. It has a slot in it that goes over a stud in the side of the rear head, and a 13mm nut goes on the stud and clamps the bracket down.

Hmm I didn't realize that is what actually held it in. I guess I may not have gotten it tight enough.

I'm going to pick up an o ring assortment tomorrow and try and get a new one on the pipe and I'll make sure I get it tightened down very tight. Makes sense. Thanks.
