So the threaded plug behind the flywheel has rusted a hole in it and I can t get it to turn to replace it
Should I drill it out or try to weld the hole up
It looks like cast iron with 1 1/8 hex in the center

I've never had to remove one so take this for what it's worth.... my inclination, if it was mine would be to heat it up modestly.
Some on the block to try to expand it and a lot on the plug to get it hot. I'd then use a spray bottle with water to direct a
stream directly on the plug and see if it will shrink or crack. Just don't get any on the block or you could crack that too. I
might try and plug the hole in the hex of the plug with tinfoil in a wad. Direct the heat inside the hex... then spray it and try
to remove it quick. Obviously the heat you've already applied hasn't worked.
If that doesn't strike your fancy... I'd probably take it to someone who can center it on a bridgeport and cut it out. I don't
think I would drill it. Cut it with a tool...

I'd heat it red hot with an acetylene torch and then let it cool, it should almost walk right out on its
own.

If that plug really rusted through, I'd be more worried about the bottom of the cooling jackets.
 
IIRC its 1 1/16th . Heating to hot will ruin oring on cam gear plug then will have oil leak. Used to have couple nuts welded together and used impact. Worked for ones in side of block.
 
I tried removing one on my early 5000 233 block with no luck. I found two grade eight 5/8 inch bolts that have the 1 1/16 hex head that fits the plug well I welded end to
end using a heavy wall steel tube. I had the engine up to temp thinking that would help. The one I wanted out is just to the rear of the injection pump. Using a 3/4 drive
set and five foot bar the plug didn't move. I've left it alone for another day that hasn't come yet...
