Yes, I did. I had no distortion at all. I did heat the block, 1 cyl at a time. I heated the block around the sleeve to start a heat exchange. Then I welded the block/sleeve. I see what you are saying about the welding rods. The welding rods I used are called Eutectic+Castolin. The box says that it is for nodular iron castings, housings and foundry defects. The name of the rods are Xuper Life Alloy. We have a local foundry that uses them on their cast iron engine blocks and according to the welders that use these rods say they are the best rods for welding engine blocks. The rods worked/blended very well with the block and sleeve, no pits, no cracks etc. Me personally, I know that there is a right way and a wrong way to reair engine blocks. I know that oven methods, and brazing is probably best. Here is why I choose the arc welder. I have my block filled with block filler, I had contacted a shop that specializes in block, cast iron repair. they would heat the block in an oven then perform the repair. They said that the block filler I used would probably melt, or harded and crack. So I decided to try a cooler method. You know, when you try to weld 2 different metals together you can see it in the weld. It will either pit, burn, or not weld at all. With this welding rod, It blended together like butter. I Tried to break the practice blocks weld, with a hammer and chislel. I could not break it, or crack the weld.On the practice block, I used a hand grinder to grind off the weld, The weld was like grinding cast iron. it was soft, and was not pitted anywhere. I did this to all 4 cyls on the practice block, and got the same result. It looks like it has never been welded at all!! I am not tring to pull anyones leg about this, I talked to my dad about the payloader iron, and he thinks that the rods would not work. I would not know if the payloader is a malable type cast. Is the iron they use in engine blocks, and the iron they use in equipment, different? Just wondering, Later ChadS
