Marshall,The cast iron boss on the block,where the dipstick tube fits into has section loss.Does the tube still fit tight?The tube has a clamp that attaches to the upper or lower threaded bolt that secures motor mount to the blockattach the dipstick tube into the boss before installing block into vehicle.Check to see if it wiggles or loose.If so, remove tube and sand clean , then clean boss to bright metal.Practice mixing the JB weld epoxy compound, once you have confidence in the mix results, insert tube , apply JB weld at base of boss, wear latex gloves, mold it around boss to compensate for missing section and. Bring it up about 1/2" above tube to boss interface, let it cure overnight in 70 degree temp.It will bond from cast iron to steel.Applied correctly with no gaps, as it hardens, that tube will be sealed.Seen it done on several engines. Mixed correctly, it will not leak.Seen it, and I have used this compound several vibration and high tempFixes.Dave & the 4 speed K.

My best idea would be to mill the boss below the broken area, extend the threads, and add changed length to the tube. I doubt this is a unique problem so would like suggestions for easier or better repair.Significant work has been performed on the block so not ready to throw it away.--Marshall Larson--Marshall Larson
