Re: Cracked Block Quastion
Telling someone about a car or anything else is very simple.
You tell the truth, or you lie. What is your word worth to you! |

Of course not, there are sound, time proven methods to repair just about everything that can be repaired. Replacing something just because it is broken, in my opinion, is a waste.

Re: Cracked Block Quastion
That's right. If you have integrity, nothing else matters. If you don't have integrity, nothing else matters.

Your picture represents why engines need valve seats. Pounded out. Number two and three exhaust seat is a common area for Model A and T engines to crack. They can be easily repaired if the machine shop knows how.! There's no need to find a replacement block as we've been fixing these now for years. What's to say the replacement block is crack free; it may be worse.? http://www.jandm-machine.com/metalStitching.html |

I, Personally think every model A engine is doomed to internal stress cracks. With 30% to 50% of used blocks lasting 80+ years and then a virtual epidemic of cracking. The castings are timed out! They probably could be saved with some exotic heat treating, but I don't know! Terry |

I am more trusting of the seller that tells me that the block has been stitched, that rust repair panels have been used, and that there is body filler underneath the shiny paint. I am skeptical of those that tell me the block is not cracked, the tin is original and no body filler. Everyone has to determined where they are comfortable with the parts in their car but hopefully the parts that are determined to not be worth fixing can be passed onto someone else that will appreciate them.

Re: Cracked Block Quastion
Thanks for the opinions guys. As for the engine matching the truck, not 100% but I do know that the engine number is the same number it is titled as. As for whether the engine was running, it was and was running surprisingly well until it wasn't. Took it apart, every babbitt is completely wrecked and the crank snapped in half at the number four journal and I didn't see anything coming prior to this happening. Now with that, I've learned I should have been checking bearing clearance every so often which I was not and did not know I was supposed to, too used to modern cars and jets I guess. However, there was less than 8000 miles on this engine since it was rebuilt so I don't know. I did drop the block off at the machine shop today to have it cleaned and magnafluxed for any other cracks. I'll keep you guys posted on what I find and decide to do. I may just find another running engine and rebuild this one at a later date, we will see.

Re: Cracked Block Quastion
That was a counter weighted crank also, what a shame.

Re: Cracked Block Quastion
JJ Cunningham: Hopefully you have had good luck in securing a block and engine rebuild for your car?
Since you've had so many problems with cracks from the rebuilder. This is how we do them rather than soldered joint, we leave to the plumbers! We even had one like yours that the JB weld,solder and an attempt to do stitching. Fortunately for the customer he came to us. |

Re: Cracked Block Quastion
How do you repair a crack that extends down 1 1/2 " into the intake valve hole?
The top has been stitched. |

Re: Cracked Block Quastion
I am here to tell you it can be welded and machined. We do this all the time with high performance engines [800 horse motor].

Re: Cracked Block Quastion
"Do you replace the body parts with new or have the repaired by reforming and welding?"
body parts don't propel me down the road Mike.... I see many on here will repair anything and I guess that's a good thing. You all have far more experience on engines then I do. I still won't buy a stitched and pinned engine and wish Ryan had left the response to my original question on here. It gave an opposing view of a guy who was screwed at purchase. His stitched and pinned engine fell apart, but I guess we don't want to hear about them apples in fairness, just what we want to hear is what we hear..... |

Re: Cracked Block Quastion
Bruce: If you refer back to my post#25 you'll see the same repair you're enquiring about. We machine the valve seat area out for a new seat repair the crack through stitching and good as new again. No welding. Ever.

As I look at that crank, am wondering: What size main/rod journals was the crank ? Doesn't 'look' drilled for pressure...was it ? Looks awful small journals, usually all cranks (that were not drilled) I've seen snap at rear main ? |
