Don't use it! It might work for a bit but not long term. Get someone to tig weld it properly, thats the only way that you ever stop the crack from coming back or even geting bigger. I will weld it for you properly if you want. If its out of the sled it no problem to fixDoes that stuff really work on a small crack leaking out from a aluminum sled engine block?
Drill a small hole at the end of the crack. Stop it from spreading and jb weld the **** out of it
No can do bob,Thanks for offer, it's not worth all the work,the crack is about 1/8 long and shouldn't spread.
