help we brought the car home 1 week ago not running , a project for my son !!!
He got it running , did the valves put new spark plugs in and we were changing the oil before we deal with the carb or vaccum leak ??? as my son was tightening down the bolt he broke the internal bolt !!!!! trying to torque it 9 lbs are we screwed and have to rebuild the whole engine or is there some macgic fix ??? Im hoping (IMG:style_emoticons/default/cheer.gif) (IMG:style_emoticons/default/blink.gif) his so bummed we just about narrowed in on our problems !!!

So sorry to hear this. I sympathize with your son. He must feel terrible.

Two questions...How are you sure you cracked it? Did you hear a pop or feel the torque give way? Is it now impossible to get the strainer bolt to 9 ft-lbs? If so, your guess is probably correct. Either the boss in the case is cracked, or where the oil pickup tube is brazed to the eye that the case bolt passes through. Either way, sorry to say that the case needs to come apart for inspection.

Possible, but less likely, that you stripped the strainer retaining bolt/nut thing (I don’t know why they call it a bolt)...in which case you just need another. Keep us posted and good luck!
