I use JB weld to repair cases at the water pump surface on a regular basis.
Pitted aluminum is not something that JB weld sticks to very well so you
need to use a drummel tool and clean the hole out and then do the repair.
if its a in van repair consider siliconing the new oring after cleaning the
surface as best you can
