[VAC] Toilet Leak

["Kit Sullivan Mac.com" <kitsullivan@xxxxxxx>]

I have a leak in the toilet of my 1962 Bambi. The problem occurs whenever I
press the flush pedal - nothing leaks out if the hole between the bowl and
the tank is closed, even if the toilet is full (I tested this with blue
holding tank deodorizer) but the moment I press the pedal to flush the
toilet, it immediately begins to ooze out from beneath the pedal. I think
the problem is with the seal on the bowl side of the little disc that moves
aside to let the contents of the toilet fall into the tank. When I was
tracking down the leak, it seemed that some (a good amount, not just a
couple of drops) of the holding tank deodorant was swept into the body of
the toilet and subsequently leaked down to the pedal mechanism and onto the
floor. I took a couple of photos of the problem to illustrate what is
happening. The photos can be found at:

I am not sure what caused this leak, although it does seem to be getting
worse. I cleaned the toilet with bleach when I first got it - could that
have caused something in the toilet to deteriorate? How do I repair this
problem? Do I need to replace the toilet? I don't know if it is the original
toilet, it is not the one pictured in the Owner's Manual that I have. Thank
you for any advice you can offer!
