Ok, when I picked up the engine that donated its head to my XJ, it had a aluminum cover. My XJ has a stamped tin one. I want to install the fancy one. The thing is the 2 connections that are on the top are busted. These 2 connections are 90 degree elbows. So now the question...How the heck do I get them out so I can replace them with good ones? I am a little stumped, as they wont pull out or thread out.
