I just can't stand it without a reply....  My 84 leaked when I bought it with
109,000 on it.  I am fully capable of welding and refinishing the surface but I
like to have a life too and didn't want to go through the hassle.  Before I even
knew about the web group I decided to try J B Weld.  IF you prepare the surface
and get the existing corrosion out, the repair seems to last indefinitely.  I
now have 202,000 on it and haven't seen a drop of coolant from the heads.  I
feel that is testimony enough.   BTW, when I did the rebuild I was amazed to
find the crank measured EXACTLY as the factory diminution. Good stuff.
