January 4, 200521 yr Ok the gudgeon plug that its under the waterpump has rusted into its hole. I have destroyed a 3/4" to 1/2" drive adapter trying to undo it with a 2 foot breaker bar with piece of pipe to make it like 5 foot. Now the allen key can turn a little in the hole but it not completely destroyed yet. My dad then suggested I drill a whole in it and try and break the seal with a punch and hammer to no avail. We got a blow torch on it then cooled it with water with no results. Hmm should I try to get it a touch hotter before cooling it?
January 4, 200521 yr You could try heating the area up around the plug then cool the plug with dry ice. If you have already drilled and destroyed the plug, you could use a large (9/16") easy-out. If all else fails, weld a large nut to the plug and take it out that way.
January 4, 200521 yr Author nah the whole was drilled in the edge of the plug so the allen key indent is still allrite.
January 4, 200521 yr nah the whole was drilled in the edge of the plug so the allen key indent is still allrite. In that case, do what I did. Soak that dude regularly with Mouse Milk (or PB Blaster). Then, I took a grade 8, 9/16" bolt with a tall head and welded it into an impact socket so the head sticks out. Used it in my 1/2" impact. Came right out. If that fails, do as previously posted.
