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?
