Been busy getting a new shop ready to open. The way I do it. Heat the pipe up until it glows. Then with a punch and hammer. Fold the pipe in on itself. It will fall out without damaging the manifold. The hacksaw blade works well. Just be careful not to damage the threads. [Reply]  [No Email]

The pipe was broken almost flush with the block. What I did was to use a hack saw blade to cut two places about a 1/2 inch apart into the wall of the pipe in the port. I then took an air chisel, caught the edge on the pipe between the cuts and chisel this chunk out. Then I collapse the rest of the pipe in the port an removed it Kent [Reply]  [No Email]

I then use an "Internal pipe wrench" that expands to grip and screw it out. I "Think" mine is a Crapsman, (It's 5 degrees here in Wisconsin, this morning...too cold to go to the shop and check) An "easy out" would work , on the heated fitting, but who has one that big!
