8BA Heartbreak
So a running flathead doesn't mean it's not a cracked flathead. I drove this baby into the shop, pulled it and took to the machine shop. got this sad news... several cracks I'm heartbroken |

Re: 8BA Heartbreak
I hear you and share your pain. I went through 5 blocks recently. One engine, also ran prior to my purchase, was cracked and two of the rod bearing throws on the crank were so out of round, you can see they were egg shaped. Floating bearings were split in two on both. Motor ran quite and cool. Amazing.
If the crack in your block is accessible (looks like it is), it can be pinned and the bore sleeved, but the folks who do this type of work are getting few and far between. The cracks between bolts and water holes are no issue and quite common. The "deadly" crack on your block is the valve seat to bore. From what I've found and read, they normally crack in the exhaust seat area due to lean mixture and a overheated charge. Don't panic yet and do a little research to see if you can find someone who can repair it. Heavy machine repair/machine shops would be a good place to start since those type of motors are very expensive and they try to fix them before replacing them. Good luck. It absolutely stinks when you get this news. Last edited by Tim Ayers; 06-26-2019 at 08:18 AM. |

Re: 8BA Heartbreak
If the machineshop was worried about the cracks going from stud to water jacket they ain´t used to flatheads...
If only one valvepocket is cracked and not to far down the valvepocket repair it ! |

Re: 8BA Heartbreak
I am chewing my nails. I dropped my block off at the machine shop a week ago and need to hear if my block is good or not!
Glad to hear it can be repaired! |

Re: 8BA Heartbreak
Mine had some similar cracks and areas around a head stud that needed to be repaired. Shop took care of it. All it takes is $$$!

Re: 8BA Heartbreak
"Ritzy1" - To be clear; did you have the "Part number" cracks (the ones between the headbolt holes and the water passages) repaired?

Re: 8BA Heartbreak
Braintree Ma, so I'm thinking if he had J&M do the block then Frank casey stitched it.
