Finding the leak

["John Hofstetter" <hofs@domain.elided>]

Joel,
It sounds to me as if your method might work, but it seems awkward.
Personally, the way that I've done it, is to remove all the plugs,
apply air pressure to one cylinder at a time with the valves closed
for that cylinder when I do it. You should easily find out where the
leak is, although I guess you really only need to know what side of
the block is leaking.  I use the rotor motion  in relationship to the
distributor cap to tell me when a cylinder is in the compression mode
and that way only have to fuss with making sure the starting cylinder
is compression not exhaust. From that point, I advance the rotor one
position and check that cylinder next.

     Whaddy'all think of removing one spark plug at a time, starting
the 
     motor and seeing which cyl is making the bubbles in the radiator,
then 
     doing a compression check on all the cylinders, as well as a
leakdown 
     pressure test and maybe make the determination that way?
