Cracked block
 

Any chance this one can be fixed? If so any leads on who would tackle job, located in Western New York.

Local machine shop says it junk. If it is beyond repair anyone that wants it can have it. Also have another block junk that hasn't been cleaned, also available. Otherwise I'll have to scrap, need to get them out of the way.

Thank you in advance for your input.

Yes it can be repaired. I have one just like it in my shop that has been repaired.
Replace the valve seat, and have the cylinder sleeved, stitch in between.
As long as the crack does not go too deep in the valve pocket.

Anyone know what typically causes a crack like this to occur?

Re: Cracked block
 

Excessive heat during an overtemp event is the most common cause.

google engine block stitching. It works, I just did one and
it's running with no leaks. G.M.

In my neck of the woods approximately $100 is what I was quoted.

It's a common crack, I've had many repaired just like it. A fellow in Mass used to do this without sleeving the block, just by stitching. Can't remember his name, but someone here might. Just remembered Frank Casey.

I've fixed one just like that about five years ago. No sleeve, new valve seat. Still running fine.

Bob, its a 49 to 53. To all others, thanks for the replies.

I have the same crack in the block in my 51 F1. Had it stitched, the bore sleeved, and a hardened seat installed at the valve. Shop pressure tested it before going any further and it was fine. Runs great.

I had Northeast Machine, Two Mile Creek Road, Tonawanda, NY do the repair and my rebuild. Extremely happy with their work. That is not a junk block, if that crack is all that's wrong with it.

Ol Ron, It's Frank Casey of Millbury MA. Cash only out of his cellar. Well he probably gets checks from a few businesses. He makes all his own tooling. Says the lock n stitch stuff is too bulky and expensive. I was there once and he was repairing a blown out section of a delahaye engine. He drilled, hacksawed and filed the patch because he said grinding hardened the steel too much to work with.

John (hulleywoodworkin), I'll take the block to Northeast and see what they have to say.
Thank you.

Try Mike Moriarty down on RTE. 19 South in Warsaw, NY. He has a shop and rebuilds engines, especially flat heads - not sure if he repairs cracks or not. I don't believe he's on the internet.

If he's close enough to you and you want his phone number, shoot me a PM and I'll give you the one I have (not sure if I have his home number or business number, so I don't want to post it here).
