What did you do to get it out? I've sprayed PB Blaster around the edge. I've hammer blowed the ears on both sides. I even put some leverage against it and broke the ear on one side. I'm only removing it to change out the nipple, but now I wonder if that will be welded in too. I would like to reuse it since it checks out good. If it doesn't come out tonight, I think I'll just shorten the nipple and use a pre-curved hose to the pi coolant tube. Any usefull suggestions , anyone?
