I have a cracked block in my 235. Crack is in the deck, between cylinders. Blows water into the crankcase. Running a zero pressure radiator cap.

Spring of last year, following the advice of Jerry (thanks) I was able to stop the leak. Used Bar's Head Gasket Repair, which contains sodium silicate without a bunch of extra additives. Followed instructions, flushed, cleaned the infamous drain passage behind the exhaust. This held until a 100 mile round trip to the tractor show at Goessel Saturday. Coming home the oil pressure dropped and temp ran about 195*.

Any recommendations for a step higher on the sealer? I don't have money to build another engine right now.

Are you getting coolant into the oil again? The sodium silicate cures best when it's exposed to combustion heat. You might want to try regular Bar's Leaks on that type of crack, the one that seals a leak with vegetable fibers and water-soluble glue. Eventually, you're going to need another block, or have the crack in the present one repaired professionally. A 4 lb. cap will force more sealer into the crack. A zero pound cap only uses gravity flow to get the sealer where it belongs. Warm up the engine with the 4# cap, then let it sit overnight without relieving the pressure.

I have used Moroso Ceramic Seal in the past, was recommended to me by a machine shop as a quick fix in a pinch. I've had pretty good luck with it but it is always a crap shoot.

K-Seal. About $16.00 for an 8oz bottle. Does not matter if you have antifreeze or not in the system.

Had a cracked head or bad head gasket one on our 96 New Yorker. Put that in three years ago with the engine blowing coolant out the fill cap.

Three years later it still runs and not blowing coolant.

I've used it on some other problems for a cheap fix and it has held up.

Worth a try.
