Can this be fixed?

[DirtyD803]

I pulled the started off of my new project and found this.

Look at the bolt on the left. can it be fixed?

If you don't know what your looking / for at then you can't help me.

Yes, anything can be fixed with enough time and effort. Here's the first three ideals I can think of.

Instant steel might hold.

Cut the rest off and weld on a coupler (long nut) with the right thread.

Weld up the area, then drill and tap a new hole.

I was thinking about doing the instant steel.

Thanks for the help

I vote, weld on a coupler.

how about install a long threaded stud with the right threads, weld it in place then install your starter and put a nut on the threaded rod to hold starter on. Did that make sense?

 

[DirtyD803]

ya that made sense.

Best ideal yet, but I wonder if he's still be able to remove the starter without takeing that bolt out.

No, not to the point you will be able to trust it.

Welding. Cast block=stress cracks around the weld area, cause you can't properly pre-heat & ping.

Ready weld or putty weld. Mabey but I think the vibrations & oils getting into it would cause it to fail.

You may be able to do the long bolt thing but then your back to the welding thing.

You may be able to thread a piece of solid rod & weld a steel tab to it & drill & bolt it in place to accept your starter bolt BUT would be very difficult to get it into the right spot.

like Jeff B said,welding isnt a good idea,if it was on a bench it could be brazed with brass(old shool),but the block would need to be pre-heated and then SLOWLY cooled down.i had a small block chevy cracked over 2 inched and used this procedure and i still have it(i brazed it back in 1989 in high school).

 

[Blkvoodoo]

that break is actually pretty common on a 4.3 and some SBC blocks.

Jeff B is correct, you "might" get a temp fix on it, but you are pretty much needing a new engine (block)

Saw a lot of those type breaks, some were even warranty when I worked at he Chevy dealer, You can bet, if GM didn't HAVE to replace the engine, they wouldn't. But under warranty, that is what happend.

 

[DirtyD803]

I just need a temp fix, something that will let me move it on and off of a trailer until I can get the $$ for a replacement engine.

Weld it up with some nickel rods, drill and tap. Make sure you grind the crack a lot and pre/post heat. Keep any nearby parts/seals/etc. cool as much as possible.
the weld should be sufficient for your use if done properly

I have something similar that has held with JB Weld for quite awhile. Not on the block, a threaded ear on the starter that broke off. Cleaned good, JB'd, ran the bolt in and back out to clean the threads some, let cure for 2 days, has held for quite awhile.

That was what I was thinking to do for a fast fix, i need to get this thing on a trailer soon since i'm moving.

 

[marvilusone]

Winch it on the trailer???????? Or pull it on there with another rig????????

Thanks, in response to the whole no welding cast stuff. I understand what your saying, but I have mig welded some cast stuff thats still holding, not saying its engineer approved, but its stronger than jbweld
