Pics for the fella who is working on his if the can type doesn't work out.

Top pic is what it sounds like he has. Loosen the hex nut and tap on the end of the heater element.
Buy a nut to screw onto the end of the heater. The one shown is the wrong thread pitch but you get the idea. Thread a four or five inch bolt into the nut and work it back and forth. A little persuasion with a hammer might be needed.
Last pic is the o ring that seals the plug. You can see how it is squeezed between the two halves of the plug.
The hole in my block was a little rough so I added rtv to the repair. So far so good

Hope you feel better soon.
I paid a mechanic who had done it before help me get it out. I thought sure the green disc must be threaded in the hole but no. The hole in the block is smooth and literally the only thing holding it in is the o ring pressing out against it.

I suggest you give it a dose of wd40 or similar while you are on the mend.
