Been stripping down a 1942 c for restoration (i guess, what a deep hole ive gotten into) and discovered a foot long crack in the lower side of the engine block, about 4 inches up from the pan. Ive looked over the forums, and see that crackes inbetween the liners/cyllinders is common, but done see anyone who has had this experience. Any thoughts? I am looking for another block, but think this may be worth repairing, if not a structural issue (worry about it breaking in 2).

Thank you in advance.

A junk-yard sucker!!!

If it were mine..... Depending on the condition of the motor. If it needs overhauling anyway, I get another block. If this one is in real good shape, I weld it. Either Braze it, or weld it with nickel. I don't care for nickel substitute.

It will have to be welded by someone with some experience, and it would be cheaper to find another block. They are a dime a dozen, and most are in good condition.

I thought you wanted to restore it. If all you want to do is patch it and want it to just hold water Bondo will do it. I bought a used car that had a water crack coated with Bondo and it never leaked. Walmart sells a putty hanging with the JB Weld that is made by JB Weld that is better than the two tube JB Weld for that kind of patch. They also sell what is marked water putty that is the same stuff. The guy on TV is selling the same thing.

SO DICK,

IN YOUR OPINION, IF I AM RESTORING IT, I SHOULD FIND A GOOD BLOCK, AND DO IT RIGHT?

YOU ARE PROBABLY RIGHT. i GUESS I JUST NEED TO HEAR IT FROM SOMEONE MORE KNOWLEDGEABLE THEN ME.

I dont plan on takeing any trophies in that this is my first restoration, and i am about as handy as my dog at doing these things, but i dont want it to be an embarassment, or break in 2 while loading it some day.

Not at all Don. To me restoring is to repair all parts needing repaired to bring it back as close as possible to the way it was new. Stitching or welding then grinding it smooth would make the crack last as well as new after painting. Patching might hold just as well.
Some will clean and paint and call it restored. Like an ad I saw a few years back. Total restoration--Like new- Smokes. I wondered if it had a favorite brand of cigarettes or the guy thought some new tractors smoked. I thought it was funny. I would have never been interested in answering and ad that was written like that.
My comment was in regard to the other suggestions how to patch the crack. Nothing wrong with a patch.
Go after your tractor with what ever you have to work with and you will be tickled when you are done with what you have accomplished as well as all that you will learned . I have been doing this stuff for years and I have yet to have what I would call a show tractor.

I've repaired many cracked blocks using a Devcon product called plastic steel. It is similar to JB weld but a stronger industrial repair product. Drill a small hole at each end of the crack. Grind a shallow groove down the length of the crack with a coarse disc. Mix the Devcon and overfill the crack. Let it cure, grind off excess and paint. I've never had one leak or come back.

Does Jbweld or similar products do anything structurally like a weld would?

Drill a hole at each end of the crack to stop futher cracking. Buff the crack area real good, cover with a layer of J-B Weld. Continue with the rebuild.

Oh, BTW, the crack does go all the way through, and is about 1.25 ft long!

Drop the pan, and see if the crack is on the inside too.

It could be stitched. Any cracks that were the length of the block probly is at the bottom of the water jacket. They can be welded but the cost of a good weld job would most likely be more that a different block. The stiching can be done yourself. You can order a stiching kit from NAPA. It is just tapered screws that are drilled and taped. After the first screw is in and tight it can be ground flush and then you center the drill at the edge of the new screw and repete until you have covered the crack with screws. You drill out half of each screw to put the next one in. Just time and a drill along with the kit. More expensive than welding if you hire it done.

hey don, my C had a crack in the block behind the genny that had been there for like 30 yrs or so as i was told by my stepfather, it was about 4 inches long and was only discovered after they started to clean the gunk off the engine, it was ok for a long time until it cracked between the cylinders. As for fixing it if it doesn`t have any oil passages or anything behind it maybe but i`d try to find another block, were are you located I may be able to help you out i`m in NY

Sounds like you have a crack from coolant freezeing and thats not good. You might be able to get it fixed but you would be better off with another block, which I happen to have 2 of. LOL

Thank you for your prompt replies. I appreciate it.

The crack is below the coolant jacket, and in the oil reservor area. prior owner(s) never covered the exhaust, and the crankcase filled with water and froze. when we tore down, the radiator and block were still filled with antifreeze, so i am confident they are ok. All else looks pretty good right now. the tractor actually looked real good, thats why i got taken (smitten)at he junk yard. silly me! I am looking for a good block, but the uppers on tis appear good, and thats why i am contemplating repair.

Oh, im in western new york, near letchworth state park (grand canyon of the east).
