The Stovebolt Site Forums The Shop Area Engine Shop Need some help - cracked block ??

I fixed one water leak and now have a drip from this lip. My question is the lip. Is that how it is supposed to be are is this a cracked block.

That’s a classic location for a long block crack
I had one just like it
Sorry for your loss
However, sometimes it can be patched up and you run a 0 pressure coolant system
I had decent luck running my truck like that with JBweld for a couple years and I didn’t do a great job on it

Unless you have some sort of deep emotional attachment to that engine for some reason (like a title with the engine serial number on it) it would be a good idea to find one without a crack. They're not really all that scarce, and the only effective way to do a good fix is to strip it down to bare bones and preheat- - -weld- - - -post heat- - - -and peen the welded crack to stress relieve the weld. Don't weld more than about a half inch at a time between peening operations.

I’m going in th JB weld directon 2manytrucks.

I’ve used it on a lot of machinery and as long as you do a decent application of it and wait for the full cure time it always worked.

In the meantime I’ll get the rest of ole Smokey put together and running.

Then I’ll look for a more permanent fix.

I don’t have room for an a frame or chain hoist in my garage and have yet to find a shop that can say they can work on a old truck.

Yeah HRL is correct
I only offer jb weld as a patch that doesn’t require removing the engine
If you take it out
A different block or a better fix is the way to go

Yep, then can put new everything in and be sure of the engine holding up for a long while..

Have a feeling it will be a while before that can happen.. space is an issue but so are funds... thats why I want to try and get everything I can working or patched before that...

Thanks for the good ideas guys.

The patch job seems to be holding ok... I let it cure overnight til noon today and filled it up... No visiable leaks...

I'll start if up in a few and let it warm up some to see if that affects anything...

Thanks for all the helpful comments guys

Got tied up working on the wiring again so didn't get to running it until this morning... ran it about 5 minutes and shut it down.. No leaks or at least no water leaks..

Now I have a oil leak at the oil pressure gauge.. can't seem to stop it.. more on that in the journal later today.

Thanks for all the suggestions and comments..

T-doug Good job on J-B ing your block,one came to me with a full length block crack patched with yellow epoxy. Ran a long time,never leaked.

Depends on what pressure is behind the leak.
In this order, worst on top:
1. combustion
2. oil
3. water

Another advantage of zero pressure cooling system and low pressure oil system.

Seems I got the oil leak stopped using Teflon tape.

JB weld is holding up great so I’m happy.

Just took a couple of pics of the JB weld repair I’ll share. So far so good.

Did you wire wheel that area before application?

No I didn’t Otto. Used brake cleaner and a brass brush. Then wiped it down with a shop rag soaked with denatured alcohol. I let it dry for a hour before applying the JB weld.

The main thing is it's clean.

yep.. prep is 90% of the job.

Most important thing to do, no matter what fix is performed is to drill stop holes at both ends of the crack.
