i cracked my block under the crank shaft (HELP!)!

can we get some pics??


a replacement case is gonna be the best repair if it did that kind of damage, there is also a method of brazing the cases back together, but i think you're beyond a practical repair
 
you said it bent something, what did it bend? I never heard of brazing cast aluminum, but i would try everything before finding a new case half. Oh and did you degrease before using the JB cause the metals gotta be cleaner than clean. Might try some epoxy.
 
idle? So it runs but does oil come flinging out the hole when running? It needs fixin anyway to prevent dirt from gettin in there. What mods and jetting you running?
 
Problem is also what got into the transmission? Metal , dirt , etc you need to drain the tranny , flush it , and clean the area and I'd suggest you use msr aluminum epoxy , it won't be permanent , but will last until you get a new case half
 
quicksteel epoxy putty !!!!!!!!
clean, clean, clean
and that bent shift rod will need replaced or that seal is gonna leak, guarenteed
 
Listen to these people, your going to need to fix it and you need to flush the transmission to get anything thats not soposed to be there out, and even if you unbent the shift rod it's not to the exact specs of were it should be so you need to fix it, if you don't do this I'll get a airleak and blow your topend, then ull have a useless blaster motor
