: I just aquired a Farmall BN that my grandfather
: restored and sold about 20 yrs ago. He had a dealership and I think this tractor was a trade in.
: Apparently the block was bad when he traded it,
: and he fixed it It must have pushed out a very large section because the patch is big. I saw him repair an H that had the same problem. It
: had a section about 8"x6" broken out and into
: about 6 pieces. On this one he furnace welded
: the pieces back together and the welded the
: piece back into the block with arc,nickle rod.
: He then finished it off with Devcon plastic steel
: epoxy. I believe this is probably what he did on my BN. The problem is after 20 yrs it is now leaking. I dont want to change the block because the casting date is correct for the tractor and the engine runs good. I have tried
: radiator stop leak and K&W block sealer and it
: still leaks. The area is way too big to use JB weld. I would like to fix the leak and keep it looking original. Has anyone had any luck with any other putties or epoxys? I have seen Pyro-Putty advertised for manifold repair, will
: it work on a water jacket? Any thoughts or comments will be welcomed.

Todd, Several years ago a mechanic friend of mine swore by a stop leak called "Bars Leak". It comes in a glass jar and has a dark liquid with pellets of some kind of fiber that desolve and flake away and build up to seal the leak from the inside. I suspect that your system is non pressure so I don't know how effective it might be. It might be worth a try. Hope you find a solution, Mark R. (southern Va.)
