I'm having difficulty trying to figure out what's missing from my engine. I got a 400 Pontiac engine in pieces and I've rebuilt it the way you would with any other american v8. The problem is that there is a hole in the rear of the water pump housing at the top and a hole in the front of the intake manifold that lines up with it. OK, I understand that water will pass through that hole but there is a gap there. I've found an O-ring in the gasket set but what is supposed to hold it in place? Should there be some kind of nipple on either piece? I'm lost.
