I am working on the heater hoses and I had the heater core by-passed with a 3/4 inch hose.....no problem.
I now reroute the heater hoses to the heater core and reattach both hoses. Now on the head the heater hose will not seal.....reminder it was fine 20 minutes ago  Now I cut the new heater hose for sure fit, use three different clamps....to no advail.... I get my trusty mirror and a flashlight out and take a peek that the nipple on the head.....it now has a pin hole in the base of it and that is where the anti-freeze is shooting out of  .........just my luck!Repair....I am thinking.......can this part be replaced?

Nipple is still made by GM and costs something like $15. I can't remember the part number otherwise I would provide it, but I bet someone here has it. It's easy to do, just take a chisel and beat the old one out. Grind a slight lip on the new one and use a socket to gently tap it in. The new ones are slightly different\thinner than the old ones, but work the same.

I got one from Pontiac Dude.I told Danee(sp)that I had a BIG order
 and she told no problem they could handle it.LOL!I think it was $25 with shipping.I took the head to a machine shop and it took ALOT of persuasion to get the old one out.
