i just got my lower engine block from the machine shop, and i wanted to make sure they torque down the connecting rod bolts, and the stupid haynes manual said to torque to 45 ft lbs, and i ending up breaking one of the two bolts. im really confused because i have been reading that i have to have them resized now? i dont get why if its just a bolt? cant i just press in another bolt and be done with it? im talking about the bolts that are pressed into the connecting rod. just to make sure. so now, as im crying...... i scratched the crack shaft in the picture shown.. is this something i will need to take to the machine shop now? or how bad is it? can i fly with it?
