[Farmall] Leaking cylinder head

[Jim Becker]

Ed,
There is one concern that comes to mind on this situation and your fix.  I 
think what you have done will probably take care of the problem OK.  If it 
is sealing the sleeve to the head, you are in good shape.  I am a little 
concerned that it may only be sealing the nut to the stud and allowing 
coolant to leak into the space between the stud and the sleeve.  If so, 
could it cause a problem later on?  Maybe rust that could make it very hard 
to pull the head later on?

I haven't seen such a problem and am just speculating, wanted to bring it up 
for consideration.
