That'* a good idea! The rag keeps the broken bits from going the wrong way.

Same with if you use heat. keep the plastic intact, if possible, and pull everything away from the manifold at the same time.

On a '93, I was able to use a wood chisel that was just about the same size - tapped it in enough to create some slots, and used it like a large screwdriver to back it out.

Either that or a large screw extractor. Measure the inside diameter, and get a screw extractor (easy-out) from your auto parts store that is that same diameter about half-way down it'* tapered length.

Oh, I see now where it broke off -- sorry, I didn't catch what I was looking at on the second picture right away (but your pics are fine). That IS a toughy.

Are you having any luck?

I was at the Twins game this evening (They lost again) I'm going to try a couple of those ideas tonight, and if that doesn't work, Echo had a pretty good idea of using a reverse threaded screw that sounded good

mine was one of the hoses by the water pump going into the housing I don't exactly remember it was a long time ago and had eatin away at the aluminum so I cleaned it (wire wheel) then put JB weld in the small cavities smoothed it out let it harden next day good as new 10 years ago and still strong, I started noticing a small puddle overnight could not find it until I replaced the upper and lower intakes.

the screw extractor stripped the plastic, and wouldn't pull the plug out, I stopped for fear of messing up the threads. I tried using a chisel as a screwdriver, and the chisel broke off into the manifold

Pull the manifold. You're probably long past due for changing the LIM gaskets anyway. It'll go alot easier at this point.
